Windows 10: do I have to re buy Minecraft since the switch over from Mojang happened?

hi I bought Minecraft over 2 years ago now and I just tried to get back on it but it's telling me I have to buy it again, I dug up the old email from Mojang just to show that I actually did buy it. hope I could get suggestions on how the fix this.

:)

 

After redeeming minecraft windows 10 gift code this happens.


Okay I went ahead followed the instructions to the "Letter" every single step and checked it multiple times.
And when i finally install minecraft i get a trial and time limit 90 minutes and it says "buy"
HELP??? This shouldn't of happened! Trying to get free windows 10 minecraft and it wouldn't work!!
(this was done in a virtual machine but performance was better than acceptable so minecraft ran smooth regardless. shouldn't effect it?)

I tried and it just wouldn't work. Tried uninstalling minecraft and reinstalling it and restarting. Nope. Still wants me to buy it. and it's still the trial.
I don't know where else to get help from because the microsoft forums don't even reply to me and mojang said it's not their problem.

 

Microsoft to buy Mojang (Minecraft) for $2.5B

Guys remember Mojang is being bought not just specifically Minecraft. They are just adding the company to its roster so expect more things to start becoming Microsoft Exclusives.

Minecraft is absolutely... boring. I played it for a few hours and never again afterwards. I also paid for the beta years ago, got locked out, contacted Mojang, but they never bothered to get back with a reply.
