Can't seem to figure out this error.  I had an existing server setup with WebsitePanel initially.  Removed that, and then installed SolidCP onto the same server (I know there is migration process, but wanted a fresh install).  We setup the customer record, and am trying to import in the existing website along with the file/folder structure into SolidCP (folder paths, and dedicated app pool config will stay the same as it is currently setup).

I've checked user permissions and almost every user that is associated with SolidCP or with the Applications pools is setup as a Admin user.  What am I missing?  Is this a problem because I am 'importing' the new website into the same exact folder that it currently resides in?  It is an issue with the existing application pools and the domain user associated with it?
