You try restarting eq2? Also, do a complete file scan- in the control panel (update screen) click on "View Details" then in there, click on the option for a complete file scan.
That should fix any problems due to your files getting messed up, if that was indeed the problem.
Ack, sounds like you've picked up that new EQ2 virus. Starts by deleting your map files, then before you know it, your character is automatically changed to a bald ogre female with hairy armpits named Immaogre and your forced to use the old EQ1 models, the ones that make people look like they have Parkinson's disease when they stand still.
