DVD Video File Reallocation Failed!

It happened to me from today and it never occured before. I did nothing weird. I also try to update to versione from version but nothing changed. I did not installed anything from when it’d work to the moment it stopped working. It happened all in a sudden. Any idea? All started after I authored a movie: I kept some extra as well as the main movie, some language and no subs. Nero started to give me an minor error: VIDEO_TS.VOB not found! :eek: Then I tried with some other film and the error now is the one I wrote in the title of this thread. After returning this error the program says that the disk might be unreadable.
I don’t understand! It never happened before and I did not do anything in between.

Please help me! :sad: :sad: :sad:
