eM Client keeps randomly interupting my STEAM gameplay

…I’m tossed out of an online play server, and there’s a popup revealing Em Client is doing something. If there is no way to fix this, there is no way I can continue to use Em Client.
Nothing like this has ever happened until I installed Em Client.

In upper left corner select “Menu”, then “Tools”, & finally “Settings”. Under the topic General" the 7th item is “Backup”. On this menu uncheck the “Enable periodic backup”.
