Internal PR all N/A

[c_t]

My home page has a PR of 4
For some reason all the rest of the pages have a N/A rating.

Any ideas why google won't spider the site?

Thanks in advance

I just noticed the same thing. On my directory which runs the version 2 series. I only have pr on the index page and none of the internal pages. Is their a reason for this? Is their any way of rectifying this?
