Config can't not be found

I started with a part that had many configs. I did a save aswith a new name to create a new part I then deleted all configs.Now every time I open the drawing to this part I always get thismessage:

"The following component configurations could not be found."
"(xxxx-xxx : part description)"
"If the configuration was renamed the same configuration will beused, otherwise the last active configuration will be substitutedin each insyance."

Any suggestions?
