Answer

That error message will be displayed whenever it fails to run for any reason. It is preceded by error messages that are more specific. So for more information just scroll up.

Most likely it is a build error, so find the red lines on the right side of editor window for each source file that has a red exclamation point on it in the projects tab and fix those lines.
