Error OPEN GL

firstly I open the launcher and click to play, when I click to play many writings appear, and one of them says Open gl: in context, which say that is the Open GL bug please help me, I'm from Brazil and I paid dearly in Minecraft.
But I found it strange that when I formatted my computer in the case of windows 7 to windows 10 Home I was no longer running the demo version of minecraft, and when I was on windows 7 I was running the demo version of minecraft and now that i bought the paid version,the paid version doesn't run either
