It's also wise to make sure you clean up, when you're done with a file. You can keep the original on your hdd or archive it on a flash drive, if you like. I would strongly recommend either using "done" when you've proofed and sent your work, and keep the file in the "done" folder only 2 days; or, completely delete it by using holding down Ctrl Delete at the same time, which deletes it from the hard drive. If you have a number of files you want to delete from "current," go into c:\documents and settings\[username]\application data\nch swift sound\scribe\current. The make the view "details" and if necessary, on the toolbar at the top, click View, Choose Details, and select Date Created or Date Modified. Since the files are unnamed in "Current" the dates and times will tell you which folder is which. But once there, you can delete multiple files from that folder.
You might also try resetting your System Restore, as I described in another thread.
