NeatWorks

I have an app called Neatworks, that allows me to scan in all my receipts and vital documents, and it turns them into PDF's and catalogs them. It stores it's data in a file called Neat Library.nrmlib located in the Documents folder. This "file" is really a package that contains all the PDF files it creates. SO I added the file (I guess it saw it as a folder/package), then I associated it with the app.
Launched Networks and it asked for my password, then mounted the image on the desktop. However, Neatworks then gave me an error that it cannot read from a read only image.
Any ideas?
Followup: So I undid the protection in Espionage; it said it was unlocking things and restoring things back to normal, and when I re-opened Neatworks, it gave me the same error... that it was read only. Something went wrong in the lock/unlock process. Fortunately, I restored the file from the Trash and it works again.
FYI, the file that it read as "read-only": I checked it in the Finder and it said it was not locked, so I'm not sure why the app thinks it is read only.
