I recently tried to install DVDFab on a new Sony Vaio laptop and just before the registration page comes up I get the following message" DVDFab the ultimate DVD copying/converting/burning software! has stopped working." I had the trial version previously and uninstalled it after it expired. It worked then. I tried the clean erase/reinstall from another post with no luck. By the way, I just purchased the registration key and installed DVDFab on a different computer in my house with very little problem other than it continued to show it's version as still expired. This was solved by manual registration key entry. I'm still at a loss as why I get the above error message on my new computer before I can even register the product. Thanks for any fixes.
