Cognos Configuration problem after CAM-AAA-0012

[kekrystek]

I installed new CRN 1.1MR3 on Windows2003 server, Java 1.4.2_10, Oracle 10g and got service started using port 9500 and localhost. Could bring up web using http://localhost:80/crn, set data source and tested successful. Tried to logon but got CAM-AAA-0012 error which said main XML document cannot be empty. I searched for how to resolve this and found that I should change to fully qualified server name, save configuration and restart. When I did this it unregistered my Cognos ReportNet:9500 and registered it with 9300 even though my configuration is using 9500 and now I can't get web to start. I get the error below:
  An error has occurred.

  DPR-ERR-2058 The dispatcher cannot service the request at this time. The dispatcher is still initializing. Contact your administrator if this problem persists. 
  Please try again or contact your administrator
========================================
Can anyone help me get past this mess. I've been struggling for several days and go from one error to another.
