I just wanted to report a problem with Google Base/Merchant Center that has been occurring all day.
If you are receiving e-mails like this after submitting your feed, don’t freak out and blame yourself. This is a Google side error, your not to blame….. …..this time 
Dear Google Merchant Center user,
On March 2, 2010 11:32:44 AM PST you uploaded to Google Merchant Center via FTP a file named “FILENAME.TXT”, but you don’t have a data feed registered with this name. Please verify that you provided the correct file name, including correct capitalization.
This is a computer-generated email. Please do not reply.

Here is a link to the:
Google Base Help Forums where people are reporting the issue:
I will update everyone once the error has been fixed by Google.
This issue was resolved. Our feeds went out this morning without error. Here is link to the help forum where Google acknowledges the problem. http://www.google.com/support/forum/p/base/thread?tid=04c2d685fe982779&hl=en
