Well I found the UnrealEd.exe, and clicked it. But I can't use it.
The computer I use to mod is one of my dad's work laptops, and its owned by the company he works for. And those chakaaryc's have something that prevents me from using the UnrealEd. I could reinstall RC on this comp, but I wouldn't be able to test the mods once they were made. This comp might not even be able to run the UnrealEd.
I need a Macintosh.
