Panic Mode

I have spent hours, I mean hours on the digital story and it is still unfinished to my expectation. This ocd is a pain in the you know what sometimes. I am having the most difficulties with converting i-tunes to mp3 files. I am also having difficulties with photo story three. It keeps telling me that my mp3 files aren't valid. It is very frustrating. I will not give up. I've come too far to back out now.
