I have some problem that, whenever I join a pickup and the bot gives me the address, and i paste that in explorer or summit (so that it launched ut2k3)...then it wont work

Also then after that failed (seeing as i always get a black screen, or the url and it stays that way untill it says connection failed), I try going there manually with the server browser/buddy list (even after deleting the stored passwords from my ut2003.ini), and it still won't work.
I dunno what to do and I already missed an exciting pickup on db-hole because of this
It does work when I go to deathball.exe and enter open *ctrl+v*address* , why is this? x_X
