client doesn't work anymore! what now?

[CløWn]

Well I just startet playing Fiesta, created a new character, played for a while, logged off. Now , about 2 hours later, I try to log in via client. Double click, enter ID and password (both correct as it would tell me if not) but everytime I click "Login" nothing happens. The window just stays as if I didn't do a thing....what now?

Would appreciate quick response

thanks
