1. Uninstall Game Maker (after putting your GM files on a floppy or CD). If this works, then its a GM problem, and I have no idea what to do, except switch to RPG toolkit. If it doesn't, move on to step 2. 2. copy all modified XMLs and maps, textures, models, etc. (everything in the folder your game refers to when you play) into a folder that is not in the Lucasarts folder. 1. Uninstall Game Maker (after putting your GM files on a floppy or CD). 3. Uninstall FoC, then reinstall. 4. Before adding files back in, TEST THE GAME and make sure it works. If it works, move onto step 11. If it doesn't, move on to step 5. 5. Uninstall FoC and EaW. 6. Reinstall EaW. 7. Reinstall the EaW update. 8. Reinstall FoC. 9. Reinstall the FoC update. 10. if you had no problems with steps 5 thru 9, move on to step 11. 11. Begin adding your modified xmls back in, one by one. Each time you add one in, test the game. If it hasn't any problems, you're fine. If not, its faulty XML I Strongly think its a GM problem; so just try step one before anything else.
