I did an installation recently of the Community Edition and it went well up to a point included below.  The site seems to be running Ok except that when I attempted to change my admin password I noticed that I do not have any of the User Account or Roles modules.  I searched to see if I could add the extension but the extension is not available.

What is the best way to deal with this situation?  How can I remove the current version and try again?  This is my first installation of DNN and I am not familiar with all the details.  I have used older versions and I have been the host for a while but this version is very different.

My environment is Windows 7, Using SqlServer 2008 R2, Asp.net 3.5.  All files and database items were successful.
