Left and trying to come back

[Mithas]

I was playing on the servers before the Kunark expansion was released. Now when I try to load up it goes to all of the way to the character select screen and says "your spell files are outdated" and "ERRORCODE SP-1". It has been a long time since I reinstalled EQ. I know I probably just have to go somewhere and turn Kunark on but I can't remember where to go. Any suggestions?
