Hello, yesterday I upgraded my Win7 to Win10. Everything was fine, I installed a few apps and they showed up in my libary. But I wanted a new and clean installation so today I made a fresh installation of win10. But now my app license are gone. For example, I claimed my free copy of minecraft win10 beta and played it yesterday but now I can't download it again, the store says I need to buy it. I used the same microsoft account as yesterday. Hope someone can help me.
