Hey Mick, I was also having some trouble with PG2 last week. I have found that if you have education in your block lists sometimes you can untick EDU and then hit update. It will then update P2P. Might have to try several times. Then go back and tick EDU list. Last week I had to uninstall on HD and then reinstall on ext. hd. Only way I could get it to work. Hope this helps
