Join Split Database

I need to rejoin a split database. I've removed all the linked tables (4) and
I've imported 3 of the 4 tables from the back end database. Unable to import
the 4th. The message is "The Microsoft Jet dabase engine stopped the process
because you and another user are attempting to change the same data at the
same time." There are no other users while I'm doing this. I'm sure I've
done this before with no problems. Does anyone know what could be going
wrong this time?

Thanks in advance for any help you can offer. This has had be stumped for
days.
