I found one but It sets all pr's to -1 and I get this information fromt heir site I am getting a lot of questions from people asking why they are getting -1 or N/A values when they use the update tool. This is because the script I use to get Page Rank doesn’t work for all servers. If I get hold of another script that does, then the PR Update Mod will be updated. There’s nothing that I can do about that, sorry! Something that may work is to try changing the datacenter, information for which is provided in the readme.txt. Here is the site http://www.directoryspy.com/downloads/page-rank-update-tool-for-phpld/
