Answer 1

None of the above resolutions worked for my instance of this error. I had just started the project, so I really wasn't concerned about the loss of it. I completed the following:

1. Selected "File\Close Project" and the project closed.
2. The opening screen to create a new project came up.
3. I deleted the project from the list just to have it not show in the list.
4. Created a new project with a slightly different name.
5. Ran the new project and it worked fine.
