I installed the user chooser ini swaping program for swapping multiple ini for different users and settings. When it installed it crashed and didn't finish installing. Now the exe for unreal ed and ut are gone . Running the uninstaller also failed.....Ut is there with literally years of  downloads and tweaks and I can't run it. Can anyone offer suggestions.............btw I have a clean install of UT that runs on my hard drive but I'd rather have my personalized version back.....please help:)
