I have the same issue on windows 7.
I've created a bug report which no one has responded to in more than a week.
I've sent 5 emails and have only been responded to once - that was to ask me to arrange a skype for help... great... but then you didn't respond to me trying to arrange a time.
As it stands I've paid $177 for nothing as the software crashes on every spin.
Please help me asap guys!
