Greetings...

If you have access to SQL Query Analyzer, this script will update her userid for you ( you'll have to notify her of the change ).  Note that this SQL handles the DNN forums too... if you don't use them, take this bit out ( highlighted ).

This should not cause an error... and should be considered a bug, in my estimation.  Please feel free to log this problem at http://support.dotnetnuke.com.  We appreciate your help.

Cheers
