HM Doesn't Work With UB

[easycome1]

Hangs up my computer, my mouse goes away. When I unload HM, all is well again.

HM version ?
You still play full tilt & it's OK there ?
What do you mean by 'hangs up' - your system freezes ?
Is that when you just open HM or when you start auto-import or when ?
What OS ? Have you updated your windows through windows update service ?
