Can't access the internet since Panda updated this morning. Can anyone help?

I have Panda Internet Security 2006 and its usually great. But this morning, it updated itself and after the restart I couldn't use the internet. I had to restore my computer to yesterday, and then disable automatic updates to get back online.

But I'd like to continue installing updates, so can anyone tell me if they know how to solve this problem? Are there any settings I have to change or programs I have to unblock, etc, to access the internet again?

(Btw I have a P5W DH mobo with wireless connection. I tried unblocking the Wifi Solo, and running the Wifi Wizard but I had no luck...)

Cheers for any help =)
