For some reason I lost PhotoPresenter, purchased from the Mac App Store. Is there a way to get it back?
If you accidentally deleted PhotoPresenter or have to re-install your Mac, please follow these steps to install an application already purchased in the Mac App Store again: Open the Mac Appstore. If you are not signed in already, click “Store” in the menubar and then select “Sign in”. After signing in, select the “Purchased” tab. Here you will find all the applications you bought using this account. Find the Boinx app in question and click the “Install” button next to it. The Mac Appstore will re-download it and install it for you free of charge. Make sure you remove demo versions you might have downloaded manually before from your applications folder, just to avoid confusing duplicates.
