I can see a continuous run of your games right up to today, including 5 games in progress and one game waiting to start. I'm guessing that the problem lies with your computer. Try logging in using a different skin (e.g. if you're playing on redhotpawn.com try timeforchess.com) and see if the problem persists. Then there's all the usual stuff, clear cache and cookies and so on. Even logging in on someone else's device.
Please come back to report results, whether or not you get the problem resolved.
Just an idle thought but it might just be a case of you needing to activate your 'game status filter' once again...press 'my games' and then down the left margin hit that filter...all games will then be evident, whether complete or ongoing...
