I'm working with the ever-relient Finale 2003, and everytime I add a new stave for an instrument, the instrument and an addition of another 2 or so go off the screen, and I am rendered uncapable of further composing my song. So, I would appreciate any help/advice on how I could quickly resolve this problem, and get all instruments onto the page.

Which program are you using? The Notepad freeware version has a limit of eight staves. (Not sure what the regular version's limit is.) PrintMusic! 2002 has a limit of 30 staves. Consult your manual (if you have one) and see if there's a stave limit.

Nope, in the full version there is no stave limit. If I have to add something, I just use that tool with the G-clef symbol and do a double click somewhere on the page. Then I customize it and it's done...I don't know anything about your problem but maybe this could help.
Finale 2003 has many errors :angry: @_@ , but the print quality is superb...

I've only ever had to do this once, but the 'add new staves (with setup wizard)' option under the Staff menu worked for me.
