I am a longtime user of DVDFAB. When I try to change my email address, I am asked for my invoice number. When I provide my Elements-5 invoice number, it is rejected as invalid (yes, I typed it in correctly!). I still have a copy of my original invoice(s) in which the purchase year is 2004.
This means that I cannot update my registration key from DVDFab4 to DVDFAB 5. Please help since I seem to be going in circles trying to get a new registration key by first updating the e-mail address.
