sh*t
as it happens with new account too i don't think it's a fault in database
suggestions:
make sure to have Triple Buffering disabled in Catalyst Control Center -> 3D -> OpenGL
make exceptions for TCP Port 1871 and UDP Port 1870 in system/router firewall, make exceptions in antivirus for java.exe and javaw.exe
clear java cache (Java Control Panel -> General -> Settings -> Delete Files)
Delete folder .haven at Documents and Settings\Username
otherwise i'm a bit clueless what can cause it on your system
