That’s what have done. I even un and re installed battle net, just to be thorough.
And that is the exact result I get. Once it crashes, no matter what character I try to log back in with, I get the divide by zero crash. I haven’t been able to do any group content because it takes too long to come back and I am usually kicked by then.
On the plus side, Oblivion and Dune released this week.
