I have the exact same problem but with the V Collection.
Safari won't open the link at all. Chrome downloads nearly the whole file 1.9Gb and then nothing. I pause/restart download and no more data comes and the file is an incomplete "Arturia_V-Collection_3.dmg.crdownload" that cannot be opened.
I've got a hardwire ethernet connection at 16 Mbps so my end isn't the problem, connection wise.
