Hijacked My Own Website?

mysiteA.com - I have had this site for about 6 years now and have always been highly ranked with a PR6 (nearly a PR7). Well, before mysiteA.com I had mysiteB.something.com this was more or less my "first web site". Well, when I started mysiteA.com I decided to put up a meta redirect to mysiteA.com from mysiteB.something.com.

Now, for the past month I have found that NO traffic has been coming from google. When I go to search google I cannot find my pages by typing the name of my site in the search engine. Its no where to be found.

I do see my site listed if I type in mysiteA.com (full domain name). Now for the really strange part.. if I put in: mysiteB.something.com it returns mysiteA.com results (with mysiteA.com as the domain). link:mysiteB.something.com also returns all of the sites that actually link to mysiteA.com.

I found this all out early last month and I have since turned off the meta redirect that I "think" might have caused this. I now simply have a link on the mysiteB.something.com that users can click to go to mysiteA.com.

mysiteA.com still shows a PR6 according to the google toolbar. However, when logged into google sitemaps Crawl stats it shows my pagerank as "low". Wouldn't a 6 be medium?

Also, it shows my highest ranked page as something that has NO pagerank according to the toolbar.

Any ideas? Did I hijack myself somehow? Is there anything that I can do?

How can I fix all of this?
