Updater uTorrent problem

I wasn't sure exactly where to post this. I've been using the beta 5 Platform since it was released, and have been very happy with the updater function. But today, a new version of uTorrent was released, and when I use the updater I get the following error after downloading the file:

"The downloaded copy of uTorrent Portable is not valid and can not be installed. This could be due to an incomplete download or other network issue. Please try running the updater again when complete"

I've tried this 3 times so far. I can't tell for sure if the updater isn't downloading all of the file, or if the file on the server is corrupt or something.
