Problem has been resolved, it was just a license issue and is working now. This is actually my third license, I already had it setup for both my brother and I on XP machines. When I went to install it on the vista machine and clicked the "get license" link, paypal only had the payment form set for $10. The automated system didn't pick that up as a full payment. I resubmitted payment, this time the form showed the correct ammount, and all is working now...

Time to quadbox, soon quintboxing

Thanks for the responses
