Oh, the irony... Tried to download Epicurious Recipes and, wouldn't you know it, download fails and restarts...
Sent a mail off to Apple and got this back:
"Dear Greg
Hi, this is Carol from the iTunes Store Support. I understand that you have not been able to download some of your iTunes Store purchases. I truly apologize for any inconvenience this issue may have caused you. I am sure you are anxious to sort this error out, so I will do whatever I can to help you with this right away Greg.
In my experience I have found that this error is generally caused by a download corruption on your local computer system. This error often occurs when downloads are unexpectedly interrupted.
I have removed the item "Epicurious Recipes & Shopping List" from your pending downloads and posted a fresh copy to your iTunes account "*****@gmail.com" to ensure the best chance of successfully downloading this application.
Before you attempt to download the new file, you will need to complete just a few steps to delete some temporary files on your computer.
In the ~My Documents/My Music/iTunes/iTunes Music/Downloads folder there will be a folder named "<track name>_<album name>_<artist name>.tmp." or "<movie name>" or "<tv show name>".
Inside of this folder there will be two files, "info.plist" and "download.plist."
Delete both of these files. Once you have completed this process I would like for you to check for purchases to restart the download from the beginning. This should clear up the error.
1) Open iTunes. From the Store menu at the top, choose Check for Available Downloads. You can also click this link to do the same thing:

2) Enter your account name and password, then click the Check button.
I hope this information helps enable you to remove the temporary files and download your purchase Greg. Thank you for your patience and understanding concerning this matter. If you do have any further questions regarding this issue, do not hesitate to email me back, and I will help in any way I can. Have a great weekend!
Sincerely,
Carol
iTunes Store Customer Support
