The client will close now ERROR

I am getting mad with this - I am on Zaken server for a few weeks, I always have to log in to l2, get an GG error, delete the GG folder, and log in again. That is how my L2 starts... Fun... But wait - after the maintenance hacking tool GG errors came, which did not fix fully till another maintenance. Everything was almost nice, until AGAIN now I made a sub-class, was getting ready to go level up, and see an error/message - The client will close now. Continue?-. Come on, can I have at least a clean week without random errors... And no, there is no maintenance at the moment, and my clan is still on playing. I have no programs only TS3, OS Windows 7 32bit. Tried msconfig.... Whenever I try logging in - push my pin code in, press start, wait for a few minutes, and see the error... =/
