Rafael, when you report a database error, you need to capture from your aolserver log file. The actual error is before the error you are showing. Tail your server log file and get the first error that shows up.
I haven't seen the line disappearing problem, but Outlook I do not have, nor have I looked at what this page is supposed to do. What browser are you using, and if possible forward, post or publish the full html that is produced that has the line problem, maybe it is a browser issue.
