Client freezes on start after update


I recently started to play this server, and its pretty nice. I've gotten to level 20 during the holiday update. Today I wanted to get back on the game and It updated, but the problem is that now its freezing and PSOBB client won't be ended by task manager. I've reinstalled and made sure compatibility mode is set. I'm running the program as administrator. My OS is windows 7. Thanks in Advance.
