my system doesnt support this, but i have spent a lot of time on a project and now it wont let me onto that project. i feel like all of my long work into making it has just gone to waste, and that all of those hours spent designing the project is for nothing.

Try going to https://get.webgl.org/ to see if your browser supports WebGL. If it works there, try clearing your cache. If it doesn't work there, try updating your browser. Also, I recommend clicking that globe icon so we know your browser and OS.
