KDE Print manager - CUPS initialization

Hi everyone I hope somebody can help - I think I broke the print manager, and does not know how to fix it. In the print manager settings for the CUPS server, I removed the server name. In stead of typing "localhost", I entered. Wallah the print manager does not open anymore - it stop on the screen - "Initializing Manager". Is there somewhere, I suppose so, a file that I can edit to put the server name back in, or is it screwed up really bad? Regards Kobus (Hope this is correct, it is my first post.!)
