Welcome to the Q&A Forum

In addition to Steve having pointed out that the PR you see is totally invalid, and not truly reflective of your real situation, I'd also say that if it's only been back online a couple days, it's way too early to even begin to determine how the site holds up.  Nowadays Google assigns an initial estimated ranking value to each page on the site, and the site overall, but then other algorithms are run over the course of days, if not weeks.  These provide additional input to either confirm, deny or otherwise cause a modification to that initial assessment. Then there's the reality that in all that time, if other sites that compete for the same phrases undergo changes themselves in that general time-frame, that too would cause shifting. Personally I don't put too much weight in ANY "ranking" data.  Whether it's MozRank, Keyword search results ranking, or any other kind.  All of it's just a general guide. The only thing that truly matters nowadays for the vast majority of situations is - am I getting a volume of organic search traffic that suits my needs, goals? And from there, is that traffic highly relevant, to the point where those visitors become conversions - meaning how many of them take that next step after arriving that I am seeking? Such as filling out specific forms, or making specific purchases, or whatever the metric is. that data, over time, is what matters way more than ranking numbers. Just my experience.
