Got a mistake on Google Webmaster Tools during removing URL

This problem was occured when i wanted to remove my old cache pages

[shamims]

I mistakenly used the Google Webmaster Tools to remove some old & useless cached pages of my site; but during doing that i pressed the entire site removing radio button on the "Crawler Access" option under the "Site Configuration" tabs, and the ultimate result is - no more new pages are indexing. But my old indexed pages (when my site was hosted in blogger) are still showing which causing a 404 towards the visitors coming to my site as I had switched to wordpress from the Blogger hosted site.

Now i want to remove the indexed pages which comprises the blogger hosted link structures along with new pages indexing that i am updating day by day.

1. How to solve this problem?
2. How can i new pages to be indexed as I made a "Entire Site Removing" request a few days ago?
3. How to tell this matter to Google Webmasters?
4. Will my site be crawled out from the google even if i submit a sitemap?

Plz help me friends.

Basically you have made a serious mistake while importing your old pages from blogger to wordpress hosting. At the point of such an migration you must use 301 redirection. Now it may take time to be recognized as newly hosted site. For such a problem you can also contact to Google Webmasters Tools website reconsideration section.
