invalid value error

As of the last week I have been constantly getting the below error.  I have been just closing the error window because there doesn’t seem to be any negative effect on the storage of messages or the operation but obviously something is going wrong. I am using Ver 7.2.35595.0

HELP…   this error continues and if there is no solution I will have no choice but to abandon EM Client which otherwise I love.

I suggest you remove the GMail account from eM Client, then add it again.

To do that go to Menu > Tools > Accounts, and remove it by clicking on the bin icon next to the account. Once that is done, add the account again by clicking on the + icon, and follow the automatic setup.

See if that makes any difference.
