Why my IPS still not compatible with FF3.6?

Hi~

I've read the announcement of the Firefox 3.6 Compatibility Update and runed the LiveUpdate several times. Still, the IPS 2.0 is greyed out and there is a red exclamation mark on it in my add-one list. I've tried to re-install FF 3.6,but the result was the same. What would I do?

 

Product Version:NIS 2010 172.5.0.127

OS:Windows 7 Ultimate X64

Location:China.

 

Thanks~
