iTunes audiobook download stuck on "processing"

I just bought this iPhone yesterday and have tried downloading a couple audiobooks from the iTunes store. I set up the account just fine, and everything seemed to be going okay until I got to the download screen and all
it says is processing. Thinking it might just be because it was a large file, I let it sit overnight, but still nothing but processing. No bar moving along, or anything. I was able to download and install a couple small apps while I was waiting on this with no problems. I am a Marine who just returned from a deployment, and won't have my internet set up until later next week, so I can't try downloading it from my computer and then synching it. Does anyone have any idea what the problem might be?
