Clonedvd Creation Error

Have been using clonedvd with no problems until now, i get this error msg:
Creation of dvd files unsuccessful:
sheduler o c /programfiles/elaborate bytes/clonedvd2eraser/pal/video_ts/vts_01_0.ifo:2:unable to open tce file.

also i’ve noticed the quality bar doesn’t show the status of dvd file.
please help newbie:)

Looks like an installation problem, please reinstall CloneDVD. If the problem persists, please send a screenshot of the error message to bugs (at)
