Scrapebox and PR Domain

I use scrapebox to scrape some Hight PR sites to commnet manually in it, and sometimes I found a blog of PR 7, 8 or 9! Wow I'm happy and go to this site and....his PR is Zero.
That happens too often, Scrapebox says that have one Riking and when you enter and wath wit some firefox pluguin theis PR is usually diferent that scapebox says.

Is there any solution to get real domain pagerank with scapebox?

SB is pretty accurate in finding PR of a page. The problem might be with the FF plugin which you use. Cross check the PR again in some other sites by manually entering the URL

The problem is that you are checking the domain rank and not the url rank.
