FB game won't load

since yesterday i cannot play one game in facebook (happy pets). the game just won't fully load. depending on the browser, the problem differs but regardless which  browser i use, the game still won't load.  i contacted the support and i was given a few tips, which i followed, and also they checked my account and from their side it's all fine, the problem apparently is in my local computer (sony vaio, Windows 7 OS). all browsers are updated and so is flashplayer.

on firefox, the loading progress bar  is complete but the game doesn't start. on google chrome the bar won't load, there's only a white, blank image and on ie, it's a black image.

the support site gave me the following tips to solve the problem :

- clean the browsers cache, clean flash cash, increase flash memory to 10 Mb, uninstall and install. I did it all with no success.

my connection is fine, and it happened overnight.i played the game the night before and it was working fine.

does someone have any suggestion, any idea what might be wrong ? i really don't know what else to look.

i don't use any firewall, other than the windows one, i checked it as well.

hope someone can help me !

thanks !!!
