[Serusers] Problem registering user with serweb

[Bob McCormick]

I'm having a problem registering users with serweb.  I click on the
"subscribe" link in serweb, fill out the form, and it mails me the
confirmation link.  When I click on the confirmation link, I get the
following error:

error in SQL query, line: 43
We regret but your test.com confirmation attempt failed.


Any idea what that means and how to fix it?
