Hi Colin,
Don't give up hope. I had the same problem (new version of
DVDFab Platinum was unable to rip to iPod) and I was finally able to re-install the previous version and now it works fine again. I'm hoping that a future update will correct whatever the problem is with 4.1.2.0. In the meantime I'm using the previous version and just clicking "no" everytime a prompt box asks if I want to download the latest version.
