Hi Brian,
If you look in the db in the mp_schemascripthistory table you will see rows for every upgrade script it has run and likely there is an error message in at least one of them.
In order to try and help I will need to know what the error message is. Then if the issue causing the error can be resolved, you will need to delete the rows from that table that have errors so it will run those failed scripts again.
Hope it helps,
Joe
