I have exact same problem. Only my hex numbers are slightly different. Once I open a project that dialog comes up and keeps coming back. I push Cancel, Try Again, Continue.. just keeps coming back. Sometimes I get it to go away. Then do a build and it comes back.
But it was working just fine until today. I did some windows updates today. Maybe that caused trouble.
