Problems running xfire

I installed xfire about a month and a half ago and it ran fine for a while. Then one day it just stopped allowing me access to the website, and it also didn't function for screenshots or chat while in a game.

I did a system restore hoping that might fix the issue but no dice. So I undid the system restore. Now, all of the sudden, xfire works like it's supposed to while in game. I can take screenshots, and bring up the chat while i'm playing. I can upload the screenshots if I want as well, but I still can't access the website. I keep getting this: Access Denied. Illegal Scripting Code Detected. For security reason, your last request has been blocked. However, the requested action already logged for further analysis.

I have no idea why I can't access the website. Any advice or ideas would be much appreciated.

Thanks in advance.
