[RESOLVED] [2008] Update query issue

[Seraph]

I'm having an issue where this SQL statement isn't updating anything.

                    Using conn As New OleDbConnection(My.Settings.dcConn)
                        Using update As New OleDbCommand("UPDATE events SET title = @title WHERE event_id = @event_id", conn)
                            update.Parameters.AddWithValue("@event_id", ep.event_id)
                            update.Parameters.AddWithValue("@title", txtTitle.Text)

                            conn.Open()
                            Dim testNum As Integer
                            testNum = update.ExecuteNonQuery()
                            MessageBox.Show(testNum)
                        End Using
                    End Using

testNum returns "0" saying it affected no rows.
I get no errors with the Statement itself.
Other queries on the DB are working fine.

event_id is an Integer and is being populated with a valid ID.

Does anyone have any ideas why this might not be working?
Maybe you see something I'm doing wrong?
