Thanks for that new redirect url. I got it working now.
I guess if all else fails, start over with a fresh UT2004.ini file. So that's what I did. Not sure what it was in there that was causing that.
I do have a couple of questions though. Is it possible to use multiple redirect urls in my UT2004.ini file?
Also, the buddies that I play with would prefer to keep the maps permanently, rather then re-downloading each map every time they connect. I had them download the maps and extract each file to their respective folders within the UT2004 directory (Maps, Sounds, Static Meshes, Textures). But it still seems to try to download it again each time for them (but not for me). Not sure what could be causing this...
