DCBS Kentucky Stories

Today i opened itunes and noticed that some of my songs wont play. its like they dont exist. If i double click on them it doesn't do anything. If 1 song that does work goes to the next song (one that doesnt) it will just skip over it. I can play those songs that dont work in itunes in windows media player. Also when i tried importing some of the songs into sony vegas 8 it says to make sure i have permission and that the file is not corrupt (something like that), and it wont let me import those songs. Idk if this has anything to do with it but right now i dont have a anitvirus program. Please someone help. If you know how to contact apple let me know. and yes i already went on there website, but there is no email support. unlock iphone 3g
