I just bought Capo on the Mac App Store, but it's in demo mode!
What actually happened is that you bought the full version of Capo from the Mac App Store, but you are running an older copy of the Capo demo that you still have on your Mac. Let's fix that!
Using Spotlight at the top-right of your screen, search for "Capo kind:app". Then, click the 'Show All' item in the list:

At this point, you have two options:
A: Delete all the non-trial versions.
You can identify which of these results is the demo version by launching all of them, and verifying that there is no "Purchase…" or "License…" items in the application menu (i.e. the Capo item in the main menu).
B: Delete all the copies, and restore the purchase.
This is the better option when there are many results to sift through. Follow these steps to ensure you only have the version of Capo from the Mac App Store:
- Drag all the search results to the Trash.
- Return to the Mac App Store application, and click the "Purchased" tab in the title bar.
- Then, locate Capo in the list, and click the 'INSTALL' button beside it.
Now you should have only one copy of Capo on your machine—the one you purchased!
