UCCDepend.exe does not do that. Although I myself have not been able to fully open it all the way (or have I...I forget), I know of certain that Epic wouldn't include an executable that does that.
Something happened apperantly when you ran it. Either your screwed around with your System.ini and made packages that were protected now unprotected...
Don't try REINSTALLING...
First, COMPLETELY uninstall...then do a scan disk, and if desired, a defrag.
didnt get your post in time, i was kinda depressed that i might of lost everything and over-reacted.
All my old mods and stuff are still there thankfully... but i installed to a different folder, thinking that was the problem, so im not sure what will happen if i copy and paste the old stuff into there.
