Minecraft isn't rekognizing that I bought Mineccraft even though I purchased it Yesterday

I bought Minecraft yesterday but was too busy to play so I waited until today when I tried playing the Minecraft launcher said you must create a username so I put one in the launcher said it was valid and then I got an error which I took a screenshot of and attached to this report.

Also when I went on the Minecraft website and signed in it didn't recognize that I bought the game.
