Game crashes at startup

[voltex]

Ok so i was messing with the video settings when i turned AA to msaax16 (I think?) and the game crashed, now whenever i start it i get a black screen and BUILD WITH UDK has stopped working. Have know idea what to do im not good with this stuff lol. Is it fixable or should i just re-install? Also the log if it helps. Edit: Tried the first solusion in this list viewtopic.php?f=34&t=72023 with no luck.

If it's just a config setting, the easiest/laziest way to fix it is to delete all of the files in UDKGame\Config that start with "UDK". Be absolutely sure not to delete the other ones though (such as files starting with "Default" or "CNC-").

Deleted all the UDK files and replaced the Default file i previously deleted and i'm back in business! Thanks! Now to get all my settings back to where they where . If changing that one option crashes the game maybe have it removed, or am i just special?

It should be just you, it is there for higher end computers which can handle the Anti-alias settings which is useful for high resolution screens

Crashes on high end computer too; there's a reason it doesn't show up as an option anymore in the newer builds.
