Third Mouse Button No Longer Works.

My Third Mouse button stopped working out of the blue. I have no idea as to what might have caused this problem. I have a Logitech Wireless Mouse M205, and The Middle mouse button just won't work, the scroll wheel works fine, i've tried looking for a solution online but have yet to come up with anything. I already made sure my Drivers are up to date. Checked the Mouse properties but no options to assign what the third button should do...I am stumped, and any help with this would be much appreciated.

It says on the Logitec site you need Setpoint installed, which you can find here - Logitech.

I appreciate the help but unfortunately it didn't solve my problem..
