Stuck in Beta after update

Em client asked me to perform an update earlier, i clicked it without really reading it. It looks like it installed a Beta version that is no longer supported, i am getting this message when i open em client now image

Problem is when i search for updates it says there are none available. How can i either downgrade back to the previous version or upgrade to a newer version?
