Problems - IMAP Error Synchronizing

Hello All, 

Was hoping someone might be able to help me out with an issue I have been having with eM. Starting a few weeks ago an error message started popping up in the logs that reads:

3:21:51 PM vande@wightman.ca [IMAP]  Synchronizing messages: For folder vande@wightman.ca/nfs0000000000640ea100015ebb

This error is reoccurring and I would like to get it sorted out.
I have posted a screenshot of the error messages.
I am using version 7.1.31849.0

Ideas? 
Thanks in Advance!

A common solution is to go to Menu > Tools > Accounts and remove the account by clicking on the bin icon. Then add it again by clicking on the + icon and follow the automatic setup. After the setup is complete, eM Client will re-sync with the server.
