Unfortunately it doesn't look like we ever received a response from the original poster nor was a support case opened so we were unable to troubleshoot or find the root cause for the original post.

This is a somewhat generic error so it's hard to make conclusions without more troubleshooting, however there are a small handful of cases over the years with similar issues, and those past cases were mostly related to volume permission issues or issues connecting to the Laserfiche server. In a couple of previous cases it was resolved by simply rebooting the Quick Fields machine. 

If you are encountering similar errors and have tried the things mentioned above, I'd recommend opening a support case.
