This appears to be a common issue with WoW. If you do a google search for error #132 you will get a pretty long list of topics, all relating to issues people have with this error in WoW. Based on the few threads I read, it seems to be due to problems with RAM. I hesitate to say that it's due to "bad memory" or "failing memory" because the people who report the problem claim that they have no problems with any other applications, just WoW. Why a video game requires higher-grade memory than any other application that you may run is beyond me, and it makes it pretty tough to figure out a solution (just buy new memory? How do you know it won't have the same issue?).
