Can't load one unity project (which I'm working on) but can load all others!

So I start up Unity and choose which project I want to use, but it won't load. So I try loading up the scene. But when I load up the scene this happens: "Unity Editor has stopped working

A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

I'm honestly not sure what to do because I don't want to do the whole thing again (even though I probably could.). So if anyone could help, please do.

(This is Unity 5)
