How had your web site been up before it disappeared? Google doesn't give out its formula on how it determines PageRank. Not sure why you are expecting PR 4 or 5. You need a lot of good backlinks to be at 4 or 5.
For a new site, that's normal. www.gtsee.com is a new site of mine, I didn't do anything for it, no inbound links, only have 2 suddomains which have many backlinks, however google indexed www.gtsee.com before the subdomains.
