How long did you wait before checking on it? On both my Wally and Hopper Duo, I have seen them briefly go back to the regular screen-saver in the middle of a download, before resuming the download. So, it is important to actually watch the download progress, and make sure that the progress bar goes all the way across. In other words, it is possible that you interrupted it in the middle of the download. Additionally, on a Hopper, even when it looks like the download is done, it is important to leave it in standby for at least another half-hour or so, to make sure that it also downloads the Joey software, etc.
