DVDFab error

When I went to run DVDFab I got an error, not sure what is was, abd it shutdown rightaway. After I restarted my computer and tried to run DVDFab it would open and close right away. After a few tries I finally got the notice of an upgrade, so I downloaded it. Now both my Lite-on DVD-Rom and LG Lightscribe burner aren’t working. When I look in the device manager it shows them there but in conflict. I downloaded new drivers but windows still uses the current ones, which are over a year older than the new ones. I uninstalled both devices and restarted hoping that would fix it, no luck. What else can I try?
