I bought a copy of Graffle last year and installed the license on my laptop. I've now been moved to work on an iMac, so I used the Mac migration assistant to transfer everything from old machine to new. I then deleted the licence off the laptop. However, I now get a message when I start up Graffle saying "This copy of OmniGraffle is not licensed. In x days this trial of Omnigraffle will require a license." The license shows up OK in the license page, I have tried deleting and reinstalling it but no improvement.

Obviously I don't want to buy another license so how can I resolve this?
