the game is on my c drive, and i've come to the point where i can try to run the game...

so it's currently under

C:\unzipped\Heroes

and what i want to run is heroes.exe, so when i type in heroes it starts trying to run the game but then goes

Unable to access the CD Drive

how can i make it not try to access the game from the cd drive if i'm not using a cd? i really didn't understand what was being said in the readme...
