Hey all! I could really use some help, I understand someone finally got the Ubi.com downloaded version to work with mods. I have downloaded the file and gotten the sound mod to work. I've tried installing the version switcher, the problem is the file is busted but I've gotten it to switch between 4.08 moded and un-moded. The corruption I have comes when i install the 4.09mb, the game crashes after about 30 seconds of being in the menu. So, my question is do i have to do something special in order to get mods to run or should I just be good to go? also on a lesser note can i get the unified installer to work. Thx for any possible help, hope i can get this fixed.
