Windows 10: Bought Minecraft Java, but cant play

I have just bought minecraft java edition but i can only play the demo mode. is this fixable and how?

Java usage to high while playing minecraft/related


Java usage is to high while playing games using java (Mostly Minecraft)

At idle java uses only using about 1-2% CPU usage, but when it comes to playing minecraft it increases to 15%-50%.

When i decrease the amount of FPS Minecraft makes the lower the percentage goes..

Here's a example of me playing minecraft:

To add to what the two above me posted, Minecraft requires Java (though there is a way to get around it, I believe). While you're playing Minecraft, Java CPU usage WILL definitely spike up depending on how active you are in the game. And to emphasize, THIS IS NORMAL.

Or maybe you need to check with the developers of Minecraft for a possible 'memory leak' with the game. Also, this is NOT the Minecraft support forum.

 

Minecraft Java

Everytime I install Minecraft the demo pops up and says to play I have to buy the full version but I have already bought Minecraft Java and I,ve tried deleting and reinstalling but it doesn't work .
