Fix broken transactional replication in SQL Server 2005

Question

I've set-up a transactional replication in SQL Server 2005 and I've disabled the DDL trigger that were created when setting up replication. After playing a bit (to understand what will happen) the transaction is broken, because I've changed a column on publisher to VARCHAR that is INT on subscriber. I've found two procedure, which will help to skip this buggy transaction

EXEC sp_helpsubscriptionerrors
    @publisher='DB1',@publisher_db='repl_test',@publication='repl_test_table',
    @subscriber='DB2',@subscriber_db='repl_test'

That gives me a resultset where I can see the error (failure on converting VARCHAR to INT)

id time                    [...] error_code error_text                                             xact_seqno
24 2012-02-23 08:33:35.313 [...] 8114       Fehler beim Konvertieren des varchar-Datentyps in int. 0x00139791000CC79C000600000000
24 2012-02-23 08:33:35.310 [...] 8114       Fehler beim Konvertieren des varchar-Datentyps in int. 0x00139791000CC79C000600000000
[...]

and I use the xact_seqno from result (0x00139791000CC79C000600000000) to execute following procedure in next step

EXEC sp_setsubscriptionxactseqno
    @publisher='DB1',@publisher_db='repl_test',@publication='repl_test_table',
    @xact_seqno=0x00139791000CC79C000600000000

which will say:

Error 20017 - The subscription doesn't exist on subscriber.

Huh?
