i have a question.

i used Audacity to take a piece out of an mp3 which shall be nameless.

i exported it as an mp3 with Lame. nomatter what i do though, i can't get it to go into my iTunes. i tried the 'add to library' thingy, but it still won't go in there.

is it just because my computer has been acting so weird lately & i need to reformat, or did i do something wrong when i saved it?
i did a good job, & i was really proud of me, till it wouldn't go in there.
