Wonder if anyone can help. My son has been playing minecraft for a long time on his computer. It is a BOUGHT copy of minecraft before anyone goes down that route. He has played it successfully until yesterday and now it throws an error when he tries to load it:

I'm not sure how to help him. I don't know a lot about this. Can someone point me in the right direction?
Edited to add that we have logged into this mojang account successfully, can't find a new launcher that people talk about. We launch it on an old windows PC from the standard minecraft launcher and it's at version 1.14.4

Post a dxdiag log http://hopper.minecraft.net/help/pixel-format-not-accelerated/support/
This is the "old launcher problem" again...
The java launcher doesn't support 1.14.4 anymore (since yesterday...)

What is the "old launcher problem"? And how was it resolved last time?
The old launcher have been fixed. Update the old launcher to version 1.6.93.
