My god you're such a noob!

Try that.  It's from the same guy that made the UT3 Tweaker that also has a cache converter in it... it was a little buggy and incomplete IMO in the tweaker though.  It would copy and rename the cache.uxx files properly but it wasn't cleaning the cache.ini file the last time I tried it.

[color=yellow:986de7d7a0]My Documents\My Games\Unreal Tournament 3\UTGame\Cache[/color:986de7d7a0] is where your cache files get downloaded to.
Cut from my cache.ini:

If you run into a situation where all the .uxx files are gone or moved from the cache folder you will need to make sure the cache.ini file is also empty except for the first line which is only [color=red:986de7d7a0][cache][/color:986de7d7a0] - having lines in cache.ini that refer to non-existent files is not a good thing.
The cache cleaner in the UT3 Tweaker also wasn't doing anything with the mutators, which are all that I have in that snippet from my cache.ini.  I have no idea if his standalone cache cleaner now works properly with mutators but maybe it's been addressed since it's at version 5 now and I think I was messing with it on version3 and below.  Honestly the stuff all works when it's in your cache folder... so if you run into any problems using any cache cleaner then just ditch it.  I don't think it's worth the headache of trying to figure out what went wrong when stuff starts messing up... using a cache cleaner that isn't 100% working just adds one more variable to a problem.
