Cannot Share Files

[cherrywine]

I receive the following message opening the database:

"FileMaker cannot share files because another user is already sharing files using FileMaker Pro on this computer."

I verified that all users listed under EDIT/SHARING had the sharing off, but that makes no difference. Appreciate any help on how to reset this to share files.

Is the database file on a shared network volume?

Is FM6 running? Is it sharing files on this machine?

The database was set up to share using Instant Web Publishing. It worked fine until the sharing was turned off, now the above message displays. The database is ran using FM7 Developer.
