Download Error 14018

So I bought New Moon(HD) a couple of days ago but i'm having trouble with the download. As the movie comes with three files, both HD and the SD version and some bonus stuff, the HD file got stuck (as it stop) during the download and i keep getting this error message 14018. Asking me to check my internet connection but my internet connection is good. I ran the iTunes diagnostics test to make sure everything was running good and i got nothing telling me otherwise, i even connected my computer to the modem itself and still the same problem. So i contacted Apple about this and the replied back with a few articles that were no help at all. My next thought was to download the movie on my computer, but i don't get the error on this other computer, the file is just stuck during the download, restarting won't help either. The weird thing is they both stop at around *65 MB* and both of the other *two files* downloaded without a problem. So my question is does anyone else have this problem with this particular download, or is it just me. Any suggestions or answers will be greatly appreciated..
