Hey John,

Thanks for writing in!

We've gotten few reports of this issue, and it *seems* that this being caused due to some sort of (unforeseen) restriction with the program being in evaluation mode (which definitely isn't supposed to happen - as we intend for the program to be fully functional through the trial). We've got an report logged for this, and our development team is looking into a potential fix.

In the meantime - I've sent you a temporary PingPlotter Pro license key (via email) that should get things up and running for you.

If you should find yourself with any questions - please let us know!

Best wishes,

-Gary
