If you purchased the DVDFab video converter probably.
If you are like me & have an older lifetime Platinum license .
That changed from what was originally purchased to only include DVDCopy & DVDRipper .
Leaving out DVDMobile which was the converter included . Then you no longer get what you paid for.
What are you going to do sue a company located in China ?
If you try that you have more money & patience than I do .
You just have to accept that you got screwed out of some features.
Try DVDFlick or AVStoDVD both freeware.
