Problem starting Recovery file

I mistakenly started a NOD file (double-clicking) from then "Recovery" directory instead of first copying it to the site directory and double-clicking. I then did it correctly and started it from the site directory and it comes up. However after I close NOF and then reopen it, I see 2 entries for my site, not one even tho there is only one NOD in my site directory. How do I get rid of the erroneous entry? I assume my mistake from initially double-clicking the NOD while in the recovery directory left some files somewhere that need to be removed.

Does anyone know how to solve this. I'm able to start the correct NOD but it's annoying to see a 2nd listing for my site when I start NOF. I'm guessing there is a database entry somewhere that needs to be corrected. Is the NOF database accessible by me? Any instructions on how to correct it?
