PC UPDATEusing MS ACCESS 2002

This thread seems not to have received any answer...
Let me try it again.

FWIW, using WinXP + SP3, MS Office XP (2002) + SP3:

In a small PC project we are using MS Access 2002.
I have an Access table that is partially incorrect in a certain field values.
I'm trying to UPDATE it, using corrected values from a different but similar table.

Found in the Archives the following thread, and changed it to fit my needs.

UPDATE Table1 AS t1
SET Vendido = (Select Vendido
from Table2 t2
Where t1.ID = t2.ID)
WHERE EXISTS (Select 1
from Table2 t2
Where t1.ID = t2.ID);

When I try to execute, Access gives me an error "La operacion debe usar una consulta actualizable" (translate from Spanish, so may not be the exact english words, but... "Operation must use an updatable query"... ) where Help is of no joy...

Of course, I'm logged as System Administrator, all rights, dedicated system...
Am I missing something?

Does anybody know if Access 2002 supports this kind of <Update a table from another table> using EXISTS as suggested for a different case in the Archives?

Thanks,
