i've been using dvdx for a while to backup my dvds as it does everything in one step

but all of a sudden i'm getting errors messages when i try to load a movie in it...

1 - unable to read from x:\VIDEO_TS\vts_02_1.vob

2 - auth.dll can't authenticate drive. disk may not be locked

any ideas as to what i can do to fix these 2 problems..... i've tried to uninstall it and clean the registry of dvdx and reinstalling it and the same 2 problems.... downloaded a fresh copy and same thing

never had these problems before

any help would be appreciated
