I was just wondering why it was showing N/A or OFF. A few people have been seeing pagerank drops so it wouldn't surprise me if it really starts updating now.
When the first person reports in with a toolbar PR increase, that's when this thread will become interesting, but not before.
Folks all the PR tools would be having some sort of technical glitches as Google has limited PR queries per hour per ip to about 3000 or so so all the PR tools are affected Due to this I have also limited PR queries from visitors in my tool(Internal Page Rank checker - http://www.livepr.info/internal-pages-page-rank3.php) So only for one site you can check Internal PR for a hour ... After 1 hour you can come back and check for another site.
