What I did was:
Go to www.google.com/webmasters/tools, and make sure your domain is set up.
Go to Google Index - Remove URL's and copy paste in the URL, and tell Google the site has been removed completely. It will send in the information, and let Google approve the changes you've made.
One problem I was having, was that you have to do this manually, so I had to copy/paste in 317 pages, so if anyone on this forum has a better solution, please do let me know!
Hope this will solve your problem
