ok so some of my itunes songs i used to be able to convert into mp3,i used to right click on the song i wanted to convert and click on convert to mp3 but i had a bit of trouble with my computer with a virus so i had to wipe out my computer and reinstall everything including itunes so i reinstalled it.and now when i click on a song to change it into mp3 form it says AAC form,and it won't let me switch it to mp3 any kinda way.i was wondering if anyone knows how to switch it over,or do i have to reinstall it all over again.some help would really be nice.i've been fighting with this thing for a few days now and it's getting on my nerves.thanks for all the help.
