Were you able to clear this?  Mine had this error when I opened yesterday and I can't get it to clear.

I am having the same issue.  Any updates?

I never got any answers on here, but I called Lacerte and what they had me do was close Lacerte program and then go into my Lacerte folder on my C drive and then into my 24Tax/Option24/EF and rename my Msgs folder to another name - they suggested MsgsOLD.  That worked, but I since have had to do that 3 more times.  But it has worked each time.  Hope this helps you as well.
