Minecraft Forums

I am hoping someone can help us here. My son plays the in browser free version of Minecraft on our desktop computer. He has played this version for months and loves it but a few weeks ago, 3 maybe, it started crashing and giving the message listed below. It appears to be Java related but I can't figure out what is wrong. Nothing physical has changed on the computer. Any help is greatly appreciated. I would simply just buy the full version but I am afraid I might purchase it but still have the same issue. We already own the Xbox360 and Tablet versions, as I said he does enjoy the game. Thank you.

There are no mods and yes it happens in making new world. It starts up and you see the game screen for a second. Then the window turns to the brown blocks and then the error message comes up.

Stupid me, I read over something in the error report. Check you key bindings within minecraft.
some are double defined. Or not assigned at all

Thank you and I will check the bindings. Where did you see that as I do not see the bindings listed in the error message?
