please post the anydvd version number (do not say latest or newest)
please post the exact error narration that you receive.
please post the drive model. there may be region-free firmware available for the drive which would eliminate the need for a software solution.
please be advised that unofficial firmware voids the warranty on the drive (if it's still under warranty)
if anydvd continues to act strangely, try enabling anydvd's safe mode and see if that helps.
please post the info above and we may be able to give you more detailed help
