windows has blocked this software because it can't verify the publ

I have a Windows XP system with Internet Explorer 6. Usually I play Spades online on zone.com. Today when I went to play the same, after signing in I suddenly I got a message saying “installing latest version, etc”. I don’t know which version it was talking about. Just after few seconds, I received yet another error message saying

“Windows has blocked this software because it can't verify the publisher”

And it wont allow me download the game any more. I tried restarting the system several times but yet getting the same error. Do anyone of you have any idea what I need to do to get rid of the same?

Thanks for all your helps.

This is the problem which occurs due to corrupt registry entries. But don’t worry, there is patch available which will help you to fix it. Simply download the patch from here http://mvps.org/nibblesnbits/files/ResetRooms.reg and save it on your desktop. Double click to ruin and press OK. Once done, restart the system and hopefully the problem will be solved.
