I have not been able to have a completely successful upgrade from 3.1.1 to 3.3.4 or 3.3.5 - everytime I cannot login with Admin nor Host.  I have verified that the DecryptionKey is copied properly from web.config - now with 3.3.5 I am getting two errors which I may have missed before.  First - when performing the upgrade to 3.2.1 I get this error:

System.Data.SqlClient.SqlException: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is 'tuấn'.
Could not create constraint. See previous errors.
The statement has been terminated.

ALTER TABLE dbo.suff_SearchWord ADD CONSTRAINT
 IX_suff_SearchWord UNIQUE NONCLUSTERED (Word) ON [PRIMARY]

Secondly I get an error at 3.2.3

WHILE @PortalID IS NOT NULL
BEGIN

 -- Transfer Portal Users
 EXECUTE suff_TransferUsersToSameContext N'DotNetNuke', @PortalID

 SELECT @PortalID = min(PortalID)
 FROM   dbo.suff_Portals
 WHERE  PortalID > @PortalID
END

To me the first error looks like an issue with the users - but I have tried deleting all users from the site before attempting the upgrade and it made no difference.  The second I am assuming is a result of the first upgrade not completing properly.  I know that no users actually exist as I once forgot to logout of the site before performing the upgrade - when I accessed the portal I still had Host privledges and could see that no users (not even Admin) existed.  Any help on this would be greatly appreciated.
