Failure to import a table to other database & make a copy in the same database

[Ray]

I tried to import a table to another database and make a copy of table in
the same database but received an error: The Microsoft Jet
database engine stopped the process because you and another user are
attempting to change the same data at the same time. It was ok and am at
loss what is wrong this time. Can someone advise the possible cause and
fix.

Thanks,

Ray
