Never mind, I figured out the problem.

Apparantly a preference setting in the Windows Store prohibited me from downloading MediaMonkey. In your preferences, there's an option: 'Prefer apps in your local language' or someting like that. I needed to disable that and afterwards I could download MediaMonkey no problem.

I'm trying to download the MediaMonkey 8 App for Windows 8. It looks great, but whenever I try to download it via the Windows Store, I get the message 'app unavailable'. I live in the Netherlands, is the app perhaps unavailable here? Thanks.
