Can't open Interactive Tutorial

When I try to open the Interactive Tutorial, I get the following message:
The tutorial could not be opened from /Users/tomroper/Documents/Tutorial.scriv. Please check that you have write permissions to the file and try again. (Scrivener does not support read-only files.)

I have checked the permissions, which are fine. I looked on the site for a downloadable tutorial.scriv, but can’t see one. Any ideas, please?

It’s possible to fix the permissions, and if this were an important project it would be worth the effort, but in this case it would probably just be easier to delete the tutorial and then spawn a fresh copy from the Help menu.

Thanks Amber, that seems to have done the trick
