After compiling a map and then going to run through it I get some error that says something about authentification library not installed or something like that. Then it exits back to desktop. I cant look at any maps I am working on or even valve maps. I can play the game by connecting to servers though. I saw a fix on some other forum, I installed the dedicated server ran it copied the file into dod:source and I still get the same issue. Is there something else that can be done to correct this?

not sure if this is the same thing or not...
