Ok so apparently my serverhoster banned me for "hacking accounts".
Should've told them that its a database, lol.
However, i managed to get a new server.
Although i expect to break again within the next days.
DL:
I'll fix my Accountcreator and will then process the new accounts for people that just bought midnight.
Thanks for your patience guys.
Also, thanks to Duelslayer1 for helping me out with betatesting the new server stuff.
