Data.myp:

The Game loads up perfectly fine, but the server never syncs up and character selection/creation never appears, tried looking for a fix but couldnt find one, i've tried multiple fixes on the forums but none seemed to help

You need to rebuild performance counters. How to manually rebuild performance counters:
1- Go to start, and type in the search box "cmd". Right click cmd, and run as administrator.
2- Type in the command console, "cd c:\windows\system32", and hit enter.
3- Then type "lodctr /r", and hit enter.

It will take a few seconds to perform the command.Performance counters should be rebuilt. Try starting the game again.

If that does not work, type
CODE: SELECT ALL
lodctr /e:PerfProc
