1 character crashing at start of combat

[hobol]

I was playing just fine, hit lvl 9 on a Halfling druid. logged for a bit and came back and now as I enter combat the screen locks up. the combat music still plays but I have to open task manager and close out the program. can someone point me in the direction of a solution? I logged into another character and entered combat just fine, so I believe it is specific to the 1 character
