Rhonda,
I've never seen this before. Could you screenshot the error you're getting and post it here?
Hopefully, you've saved your session when you began. If so, you could try closing the Fashioner and reopening the session from your account My Fashioner Sessions. Whatever is going on could clear out with a re-open. Although this might work, I'd still like to see the error and try to figure out what happened.
You could also just try to step back a couple times to see if it clears without going out of the session and back.
Please let me know how it goes.
