Strange complier error in simple RPG

I am doing a simple RPG game, but everytime I compile it it gives me this strange error:
RPG fatal error LNK1201: error writing to program database 'c:\Carlos Documents and Settings\Carlos Documents\Visual Studio Projects\RPG\Debug\RPG.pdb'; check for insufficient disk space, invalid path, or insufficient privilege

I have about 1 GB of free space in my hard disk, it is the right path, but I dont know what it means by insufficient privilage...
Anyways, here is my code:

Code:

#include <ctime>
#include <iostream>
#include <conio.h>
using namespace std;

struct ENTITY
{
	int HP;
	int DEF;
	int ATTCK;
	int SPEED;
	int EXP;
};

int PlayerLVL = 1;
int MonsterLVL = 1;
ENTITY Player;
ENTITY Monster;

void DisplayStats(ENTITY Player, ENTITY Monster, int PlayerLVL, int MonsterLVL); // to check variables are set right

void PlayerR(ENTITY &Player, int PlayerLVL);

void MonsterR(ENTITY &Monster, int MonsterLVL);

int RollDice(int DiceSides);

void Battle(ENTITY &Player, ENTITY &Monster, int PlayerLVL, int MonsterLVL);

int main()
{
	float round = 0;
	char Option = ' ';

	Player.EXP = 0;
	Monster.EXP = 0;

	while (1)
	{
		PlayerR(Player, PlayerLVL);
		MonsterR(Monster, MonsterLVL);

		Battle(Player, Monster, PlayerLVL, MonsterLVL);

		cout << "Press \"q\" to quit. Any other key to continue." << endl;
		Option = getch();

		if (Option == 'q' || Option == 'Q')
			break;

		if (Player.EXP > (20 * round/3))
		{
			PlayerLVL++;
			Player.EXP = 0;
			cout << "You grew a level! You are now at level " << PlayerLVL << "!" << endl;
			getch();
		}
		round++;
	}

	return 0;
}

void DisplayStats(ENTITY Player, ENTITY Monster, int PlayerLVL, int MonsterLVL)
{
	cout << "Player: " << PlayerLVL << endl;
	cout << "HP: " << Player.HP << endl;
	cout << "DEF: " << Player.DEF << endl;
	cout << "ATTCK: " << Player.ATTCK << endl;
	cout << "SPEED: " << Player.SPEED << endl;
	cout << endl;
	cout << "Monster: " << MonsterLVL << endl;
	cout << "HP: " << Monster.HP << endl;
	cout << "DEF: " << Monster.DEF << endl;
	cout << "ATTCK: " << Monster.ATTCK << endl;
	cout << "SPEED: " << Monster.SPEED << endl;
	cout << endl;
}

void PlayerR(ENTITY &Player, int PlayerLVL)
{
	Player.HP = 20 * PlayerLVL;
	Player.DEF = 3 * PlayerLVL;
	Player.ATTCK = 5 * PlayerLVL;
	Player.SPEED = 5 * PlayerLVL;
}

void MonsterR(ENTITY &Monster, int MonsterLVL)
{
	Monster.HP = 25 * MonsterLVL;
	Monster.DEF = 1 * MonsterLVL;
	Monster.ATTCK = 5 * MonsterLVL;
	Monster.SPEED = 6 * MonsterLVL;
}

int RollDice(int DiceSides)
{
	srand((unsigned) time(NULL));
	int Roll = rand() % (DiceSides + 1);

	return Roll;
}

void Battle(ENTITY &Player, ENTITY &Monster, int PlayerLVL, int MonsterLVL)
{
	bool PFirst = true;
	int Roll1 = 0;
	int Roll2 = 0;

	Roll1 = RollDice(10);
	Roll2 = RollDice(10);

	if ((Player.SPEED + Roll1) > (Monster.SPEED + Roll2))
		PFirst = true;

	else
		PFirst = false;

	do
	{
		if (PFirst)
		{
			system("cls");
			DisplayStats(Player, Monster, PlayerLVL, MonsterLVL);
			
			cout << "You have attacked the monster!" << endl;

			Monster.HP -= (Player.ATTCK - Monster.DEF);
			PFirst = false;

			getch();
		}

		else
		{
			system("cls");
			DisplayStats(Player, Monster, PlayerLVL, MonsterLVL);

			cout << "You have been attacked by the monster!" << endl;

			Player.HP -= (Monster.ATTCK - Player.DEF);
			PFirst = true;

			getch();
		}
	} while (Player.HP > 0 && Monster.HP > 0);
	
	if (Player.HP > 0)
	{
		cout << "You killed the monster!" << endl;
		Player.EXP += 10 * MonsterLVL;
	}
	else
		cout << "The battle is over... " << endl;
}

Thanks in advance.

What OS are you using? If you're using 2000/XP, try logging in as an admin.

Thnks a lot, logging in as an admin worked.
Now I just noticed the function RollDice always returns 9, why is that?

[EDIT]
Actually, every time I compile, Roll1 and Roll2 have the same value, I even changed it and they are always the same.
This is the changed code:

Code:

int RollDice(int DiceSides, int &ROLL)
{
	if (ROLL == 0)
	{
		srand((unsigned) time(NULL));
		
		return (rand() % (DiceSides + 1));
		ROLL++;
	}

	else
	{
		srand((unsigned) GetTickCount());

		return (rand() % (DiceSides + 1));
		ROLL--;
	}
}

I don't know what you're doing but if you inclued windows.h you can do this to seed:

Code:

// bla bla bla

#include <windows.h>

srand(gettickcount());
int wang = rand();
cout << "COOL RANDOM NUMBERS!" << wang << endl;

Edit-
What I mean is I don't know what you're doing to seed. If it's always the same I guess it doensn't work, so try that.

Only call srand( ) once, at the start of main. It will lose its randomness if you call it everytime you generate a number.
