Hello. Since a week that I'm trying to solve this problem without succes.

I'm talking about the unity3d engine. Everytime that I create a new project or add a script or stuff i get this error:

I already reinstall unity, fix registry, even I format my pc to descart that it could be a system problem.

Do you ever had this problem? How to fix it?
