It is a good program (as I was once a happy PHP Live camper), but as others have mentioned try http://www.helpcenterlive.com It's has the same features as PHP Live but It's Free!

Trust me, you will not be disappointed.. I've been using them since the beginning and been spreading the news ever since.. It's really shaping up as the premier live app. Their WinApp is even cheaper than that of PHP Live' ($35.00)...
