I finally did recall. Actually what you recommended is what I was already doing and it was failing. Even though I opened the database exclusively, it was telling me that I needed exclusive use before making changes. I know it doesnt make sense.
To correct this I had to "clean up" the database. But this was not available on my menu.
First I had to
USE mydatabase.dbc exclusive
just like a table
then pack it,
then clean up
then I can open mydatabase exclusive and access the RI
