Weird error with my shaman

[Xsiisx]

Ive been leveling up my shaman for the past week or so but the last two nights Im getting this weird behavior in the game. Ill get into combat and run back and forth rapidly or just stand in position while being attacked. My log is below, can someone help me out?

It looks like Shamwow is either encountering an error or it thinks it's not in range. Are you attacking range things? where are you? Have you tried to reinstall ShamWoW? Also what spec.

Update your Hb btw
you are on an old version

One of those two things seemed to have fixed it, thanks.
