So I ran the launcher. Update 59 hotfix began, hit a strange error (I didn't catch the error code). Had me restart and run again with full system check. I log in and get the follwing:
Authenticating...Failure. Incompatible client version. Please quit, restart, and retry with "Full System Check." If problem persists, click on the Support button.
I do this and I still get kicked back to the Login prompt.
What did you do to the game Rare! :-O
