I've been playing on hell's perp server yesterday, today i keep rejoining because i get the same problem again and again, each time i join , it takes a shitloads of time to load the server and it freezes at ( retrieving server info)

Is it normal that it takes an eternity?

Btw when i deleted the process to quit gmod 10, a message appeared , perp could not be loaded, so what do i do guys?

Well it is kind of normal for it to freeze at retrieving server info but check if you have a good connection to your modem/router. Does it say something like "Connection failed after (#) retries"?
