Sorry to hear of your difficulty, but what you're trying to do is really easy.
1. Open Finale 2005.
2. Either from the Launch Window or from the File menu, choose Open.
3. In the dialogue box that appears, pull down the menu under Files Of Type, and choose MIDI File (.mid); this is so that Finale will actually look for MIDI files...otherwise it will only look for .MUS files.
4. Navigate to the drive where youre MIDIs are - probably in your case through My Computer.
5. Click on the desired file.
6. In the dialogue box that appears, I recommend leaving all the defaults alone, unless you REALLY know what you're doing in there. The defaults are most favourable 99% of the time anyway, in my experience. Click OK.
7. Your MIDI file appears as a Finale document. SAVE the file as a .MUS document as soon as possible.
Unfortunately, any articulations, expressions, text information, etc. will be lost, and you'll have to reformat all your staff attributes, such as brackets, staff names, etc. - you'll have to do all of that over again, I'm afraid. But at least your notes themselves are preserved. It's a small price to pay to avoid having to enter everything again completely from a hard copy...or (gulp) the unthinkable alternative, that everything was lost completely.
Hope that helps.
Well, I'm off to do a backup...
