You could see if the user that uploaded it can share the parent folder in dropbox, and then you should be able to use the dropbox web interface to just add it to your own droppbox.
Of course, I'm not sure why it says it'll take a year... I right clicked the link, and clicked "save link as..." and it downloaded in 15 seconds. On an old computer here at work. It's only 12MB, which is much smaller than some CoH patches, so assuming you have a computer that was able to play CoH, it shouldn't be an issue.
