Error when logging into KDE

[DavidMarcus]

Does anyone know how to fix this.
Everything was running fine, I changed the name of the computer,forgot 
to change the alias, rebooted and got this. Now everytime I login into 
KDE I get this error, it is even worse in gnome.

Fedora Core 3
Dell Lattitude 800
