Hi all.
I just installed Demigod after getting the half off deal. I'm able to create a profile and get to the screen where I can select my demigod just before launching the map. As I launch the map or a bit before I try to launch it, it crashes and sends me to the debugger. The last line is:
section.warning: 00:00:46: Granny: Win32Subsystem (c:\Work\forge\main\code\src\libs\granny\win32_granny_windows.cpp(64): CreateFile failed with error "The process cannot access the file because it is being used by another process." at c:\Work\forge\main\code\src\libs\granny\win32_granny_file_writer.cpp(195))
This has happened using skirmish and tourney and after a full restart of my machine. I also verifed the files once. As far as I can tell, I can't play the game in any way which is sad. 
I'm also running windows 7 64bit with a 8800 GTS. Also dual core pentium chip if it helps.
