Clarion 5

I have an issue i need to have fixed real soon.
Im working on a program for work. Im done making the changes to the program. The only problem is that the compiler wont update the old .exe file.
So none of the changes stay. Well they do in code just not when the program is being ran.

If you could help that would be great.

Thanks,

The only time i get an error is when i remove the original .exe file so that the compiler will create a new one, it says "invalid or corrupt dll", but doesnt say which dll.
