Cannot login after Windows Update

[Maxxramas]

I am getting this error after a windows update. I have never had trouble logging in before, and no other games have been affected. How might I get passed this to play?

"Windows - Application Error

The instruction at 0x00000000077305666 referenced memory at 0x0000000000E8E4B62. The memory could not be read."
