I have DVD FAB 7 (the Free version) installed on my computer and it works fine. I installed DVD FAB 8 QT (the free version) in March of 2011. It wont even open up. it just sits there and acts like I didnt select it and sometimes it locks up my computer. I have tried updating this about three different times with three different updated versions and I always get the same results. I am running Windows XP service pack 3. I have an older computer if that matters. Does anybody have any idea what I can do to fix this?
