Sorry to hear that. It leaves prior Cycberlink customers with quite a dilemma:
Install the trial / PD9 retail and lose the stability and integrity of the PD8 prdocut which took many updates and many nearly a year to (finally) fix properly
or
Do not install the trial / new PD9 and wait for Cyberlink to get its act together
or
Deal with having a dual boot / backup strategy to install and try PD9 and then revert back to PD8.
For whatever it is worth, as an owner of Vegas (7,8,9, and now 10), they made a much better decision to allow both old and new to coexist. I wish Cyberlink had done the same.
My current thought would be to hold off buying or trying PD9 since it is extremely clear that the quality control and beta testing are still in their infancy.
Thanks Jeff and Nicholas for your replies.
