Linker problem in MicroSoft Visual C++

Hi.

Please help me. I'm doing some programming involving DirectX.
Everything was working out just fine when all of a sudden the compiler gave me this:

--------------------Configuration: projektDelta - Win32 Debug--------------------
Linking...
LINK : fatal error LNK1168: cannot open Debug/projektDelta.exe for writing
Error executing link.exe.

projektDelta.exe - 1 error(s), 0 warning(s)


I had been able to compile and run the program many times before and the compiler didn't complain.

Does anybody know what's wrong and how do I fix it?

Best Regards,
Christer

If the program is open, close it and then try to compile it. I did that once and it gave me that error :(

>>If the program is open, close it
Check the task manager too (or whereever you see your running programs), if your program is listed, kill it off. If all else fails, a reboot should do the trick.

Yes...that's exactly correct. Close the window in which your program is running.
