Hello, I'm not too much of a techno person!

I have the 2010 version of Finale and I'm trying to save a composition in MP3 file but I can't...

When I look in the Help section, it is said to go to the File tab, and select "Save Special", but I don't even have such an option in my menu (my version is in French, but nothing seems to correspond in anyway to a "Save Special" option.

All I can do is save the Audio File, but once again, in the Help section, they show 2 radio buttons at the bottom of the window, one of this button is to save in MP3 file, but once again, I don't even have that on my computer...

(Also, in order to have the score playing in a "better way", I have selected the Garritan settings so it sounds like there is a little bit of reverb. Could that affect in some way? If it does, is there a way to save the composition so I can either burn it on a CD or put it MP3 with the sound sounding nice, like if it was playing in a concert room?)

I know, asking a lot of questions!  ;)

Could someone help, please? That would be greatly be appreciated!

Thanks,

CB
