Reunion is in "demo" mode, but I already purchased Reunion 11.

This means that your Reunion 11 license code is missing.

This can happen when you get a new Mac, when you initialize your system hard disk, or if you use apps like CleanMyMac3 or MacKeeper (these apps will delete your Reunion license code).

Note: If you use CleanMyMac3 or MacKeeper, be advised that these apps will delete your Reunion license code. Visit this page for more information.
