Not sure where to put this but...

I got a bunch of awesome **** working today and am happy with it. I then close the editor after making sure everything is closed. I decided to take a another look at it a few hours later after some gaming.

Great now I cant compile or run the project. I get this.

Great so now what do I do to fix this? I make backups every day.

edit: The problem seems to be random and has gone away after trying a few times. Really strange. Can anyone enlighten me on the nature of this?
