I did review the following post on the General Questions forum which is the issue of not being able to get past the first step of the wizard (e.g. it just keeps refreshing when you try to enable Ajax).

Unfortunately the solution of file permissions and manually addign the line to the web.config file have not worked.  Just to try and get it to work I have set the file security permissions to full for the "Everyone" user for the web.config file.  That didn't work.  I then added the following line to the web.config file:
""

After doing that I get the same result which is the page refreshing but never getting past this step when it should have bypassed this step altogther. 

I'm not sure what else to try.
