DVDFab or Burner gone bad

I have been using DVDFab for quite some time with no problems. I would get the upgrade message, but never would upgrade. Recently, I came across a movie I could not burn so I upgraded to DVDFab
I got the movie to burn fine after the upgrade, but now I’m not able to burn anything. It copies the movie to my hard drive just fine, but when it goes to burn the movie on disc, it fails to burn and says that it cannot read the media. I have tried switching the discs, but I get the same thing.
I have a LG Electronics GSA-2166D burner. I am using Verbatim DVD media. Is this an issue with upgrading to the new version of DVDFab or has my burner gone belly up?
