Trouble with saving file...

[pyrostar]

So before i had been using audacity and it was a windows xp and it was working fine till i got a new computer which is a vista and after i download audacity it always just saves one file when i export it as an mp3, i have downloaded the LAME as well, but the same problem is that i can just save one mp3 file. is there any way i can fix it? btw i just change the pitch to the songs and try to save them as mp3, but the only one that worked was the first one whenever i saved the others it doesn't show up on my computer.

Audacity will Save or Export multiple files from one performance if you place labels inside the performance -- one label at the beginning of each song. File > Export > Multiple. Other than that, Audacity always exports one performance.

You can pick what Audacity Exports by drag-selecting a portion of a performance and then File > Export Selected.
