I have a similar issue but not quite the same. I have DVDFab Platinum 4. It runs OK and copies OK (it’s my fav burning program except for this issue!).
Everytime I try to close the program though, it completely locks up my PC. I’m running Vista Home Premium. Everything is great until I attempt to close DVDFab (before or after clicking “Finish”), and then the hard drive light turns solid (but doesn’t sound like it’s thrashing). I can leave it like that for 15-20 minutes and nothing - the mouse won’t move and the keyboard won’t respond; CTRL+ALT+Delete does nothing either. I have to kill the PC and then turn it back on again. Any ideas?
There may have been a problem during the install,…I would say do a Clean uninstall following the guide below in my signature and follow the steps completely ALL steps
then re-download a new install package don’t use the one you already have may have been corrupt during download and reinstall also you will need your registration Key handy
