ITunes authorization problems?

go click on your iTunes account at the top right corner when you go to the iTunes store and then go click something like receipts or past purchases and then it will show you all the things you bought. If you really did buy the songs then go take a screenshot of it and email Apple with the screenshot. If you illegally downloaded with limewire or any other source it means that you have to find where the file is so look for the file and then click options on the song and then scroll down to where it says find source and then replace it.
