It's been a few days now that when i enter a game the game window crashes right upon my entrance (i hardly manage to see the pieces and it disappears) and i get a new ad window.

I have lost already about 10 games on this (when i reenter the site i find out that it has made me loose the particular game)and imagine how many points:((! 

Could you please tell me what to do. If i need to download or update anything would you please give me a link.

Please help me.
