you're a champ for going through this to fix this on short notice, but for some reason the game wont open again. I checked the files for those "trov" files and they arent there as you said, so I think something else is causing the game to refuse to open when I hit the .exe file..
EDIT: I tried extracting the game files into a new folder and the game works now. You may need to update the post to include that in the instructions
Noted. Many thanks for all your help on these issues.
