Getting a "Fatal Error" everytime I try to open a game.

I was working on DL when it happened, not sure if it has anything to do with it, but now I can't open any game, even if I open a new browser.

There are a few more threads to this problem. See:

Sorry you’re having trouble—this error appears when WebGL is not enabled in your browser. Dynamic lighting uses WebGL, a Javascript API for rendering high-performance interactive 3D and 2D graphics without the use of plug-ins. WebGL is available on most computer systems and is supported by Google Chrome and Mozilla Firefox, the browsers for which Roll20 is optimized.

On Chrome and Firefox you’ll need to turn on Hardware Acceleration in your advanced settings. You can test whether WebGL works using this link. (Also posting this to the other threads!)

It seems it was an error with my graphic card crashing, I reseed the PC and now it's working properly.

I've encountered the same error, I'm on chrome PC.  I hope that I don't need a new computer with a better graphics card or something like that. Is this not enough? :

Any help is appreciated I've been trying to figure this out for a good while now, and I would love to be prepared for my next game.

I've been dealing with this fatal error issue for three days and I really don't know what to do

I am posting this to combine these into one mega-thread:
