ScrapeBox Errors Harvesting and Always returns PR of 0

I'm having problems with Scrapebox all of a sudden. I hadn't changed any settings and for some reason my harvester is getting tons of Google errors. I only have 3 coections enabled and I use proxies, which all test just fine.

Also when I try to get URL pagerank it comes back as 0 for all pages.

I'm really quite confused as to what is going on. I had another set of proxies that I tried out and I'm having the same problems.
