WotLK Crashing near a spot on

Long story short:
- doing totem quests on my new shamans
- all 5 crash at once
- log on with normal client (non-multiboxing one)
- i kept crashing
- tried non wod model client as well, kept crashing
- use the character unstuck to get them all out of that area since the second they logged in they crashed
- and now they're fine

So i'm guessing that i had some sort of corruption occur when i downloaded my game client? and maybe redownloading will solve this? if anyone else has had this problem please let me know.
