My teenage son purchased DVDfab last December, back when the product still offered free upgrades. He has been trying for a couple of months now to request a registration code to get the upgrade to version 5 but they never respond. We even gave them a second email address in case the first did not work. Yesterday, I copied and sent to them a copy of our receipt! Does DVDfab still send out requests for registration keys? Has anyone else had this problem? Thanks a bunch.
