Error message after upgrading VB to 3.7.3

[mike parsons]

Chuck,
This was brought to my attention by one of my members. When adding a comment the following message is displayed. Any ideas how to fix it? I imagine a query would do it, but what query to run to add the unknown column?

We're sorry, but the system experienced an unrecoverable error. Please try again later.

Script:

Query: INSERT INTO pp_messages (msgid,userid,fromuserid,datestamp,message,type,photo) values(NULL, 11086, 15, 1221570866, 'Mike Parsons has added a comment to your photo Double_crash_on_8-8-2008_004.', 'c', 3973)

Result: Unknown column 'fromuserid' in 'field list'

Database handle: Resource id #45
