Invalid sequence value

I am getting an error window pop-up every time I open the eM Client app (version 7.1.33101.0) on my Windows 10 tablet.  The error message says “Invalid sequence value”.  I’ve already tried the Repair function in Properties and this did not resolve it.  Here is the log:

Hi Peter,

Please try removing and re-configuring your GMAIL account in Menu > Tools > Accounts and check if the problem persists. As it’s set as IMAP, your data will be pulled from the server when you reconfigure it in eM Client.

FYI.  I reported the above problem after several days of getting the error message.  I went in today but before I could try to apply your suggestion, I am no longer getting the error.
