how do I unlock a database

[wordmuse]

Hi -

Big problem. My main URP database is somehow locked.

- I am the only user.
- It wasn't locked yesterday.
- I've uninstalled and reinstalled URP
- I've rebooted my Windows 7 Home Premium system twice.
- I've tried saving the file to a new name.
- I've tried using Windows Explorer file copy to create a new file.
- Other databases aren't locked and work fine.

I'm reluctant to try and copy and paste items from the locked to an unlocked because internal links will be broken. But I find I can't even do that.

Any ideas about how to fix this?

Thanks.
