ARG!!!! HELP! (TrackerUl.dll problem) Help Fast!

uhh i was trying to join a LAN game and as soon as i got in a game it said Connection_error or somthing like that in the upper right hand corner of the screen then i droped due to time out and the consol said it had an error reading the file TrackerUl.dll or somthing like that. can anyone help?

err 137 views and no replies, wow..

anyways. give us your system spec. have you deleted afew files, do other mods work, are you working off cs retail or hl base?

Don't worry i believe that file is for finding friends that play ESF too.That message is also displayed on my screen,but it doesn't seem to affect anything.
