trying to delete one computer from services and adding a new one

I am trying to delete one computer from my account and add a new laptop in it's place. When I go to the devices section in my account the computer that I am trying to remove seems to be stuck with a "unistalling" status remark.  NIS has been uninstalled from the old computer but when I try to download NIS for the new laptop I get the following error: Error ID: fedc1a4b-4845-4310-b73c-541943185564.  How can I get services to show the old computer as deleted and download NIS on the new one?
