I am in a similar situation, Cyberlink have told me that they are currently sending out info to those eligible for the free upgrade (purchased 30 days before release of PDVD11) I was told to get in touch with them if I have not received anything by 31st May.
Hopefully I will have the upgrade in the next 2 weeks
