I wanted to create a Realm for me and my friend. I haven't claimed my 30 day trial version.

The Realm icon in my worlds list disappeared and when I tried to create a Realm, an error window popped up saying ,,Unable to connect to Marketplace. Maybe check your Internet connection?'' I checked my wifi connection, it was all fine.

Then I tried to reinstall Minecraft, but when I opened it again, all my worlds were gone and problem unsolved.

Please help.
