Device not Supporting the Game?

Hello Chaps, I have an issue here: today, I opened the game, and it read a message as follows:

Your Device can not support modern graphics and the game. Please update browser, ect.

I did that, and now it says:

Your Device can no longer support high graphics, so we atomatically switched to low graphics for you. When I turn on high graphics, It auto-reverts to low graphics.

Is there any solution to this?
