Not able to move

I use a webtv and for the last three or four days I haven;t been able to makea move on any of my games. I can still be challenged but when I go to any of my boards, I can make the move on the board but when I click on the move button it doesn't register. Any suggestions?

Apparently Webtv updated their system and it messed things up for this site. I tried moving on a system that wasn't updated and things worked just fine. Thanks,
