I'm getting some error and cannot open my User Preferences window anymore.

Now when I try to open it by selecting File > User Preferences, a popup displays "Failed to open window!". The console displays:
Win32 Error# (3221692624): <no system message>
I've tried restarting my computer, but that didn't help. I've also tried deleting my script from
What can I do to restore my User Preferences window?
