DTS copy all objects failed with invalid column name

I am trying to use the Import Data wizard to copy one database into
another on the same server and keep getting this error.
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name
'ColumnName'
There are 6 columns in the list and all of them either don't exist
anymore or have been moved to another table in the database. I don't
understand why it keeps trying to copy columns that either aren't
there or have been moved. It looks like the database has become
corrupted. Does anyone know how I might fix this?
Regards,
AaronI have also tried dropping all the tables, recreating them and
re-inserting the data and I still get these errors when trying to copy
the database.|||I have also tried dropping all the tables, recreating them and
