Peggy B,
I have just upgraded from PD 4.0 to 6.0 and I too ame getting the same error. I used PD 3.0 initially and have been using PD 4.0 with great success for the past several years. I have not encountered any problems with either of these 2 versions.
I have submitted a trouble ticket to CyberLink support, but hve not received a reply. Have you contacted sypport about this issue?
If I don't get a resolution for this problem, I will uninstall it and go back to version 4.0. Then all I have to do is get my money back for the upgrade.
I noticed that it's been several months since you posted this and I didn't see any replys. Good luck with your issue.
Leroy L.
