Game scripts error please help!

I was making my game, when suddenly today, all scripts say that they could not be loaded, and that I need to fix them. And I get a shader asset error: unexpected char 0x0. All was working perfectly yestterday. What happened? Help10902-capture.png

Well the thing is,(sometimes happens to me) you have made a script that has errors, in order to fix those you have to either, delete the script that is affecting the unity3d editor or fix it.
