Thank you for the response.
When I click on Commander start it says "cannot find SH3.exe in this folder."
I cannot find in my game directory folder. I think it got deleted. Tried to use my game DVD to repair but it won't work. Do I need to reinstall everything at this point?
I haven't played SH3 in years, and love this LSHIII mod after installing and playing one patrol. It's like a totally new game.
