Replying to this year old thread even though you probably won’t see it, just to let you know I’m going through the same thing.
My laptop died and I got a new one. I have the Absolute collection on a desktop, with the usb license. I wanted to be able to use Absolute on the laptop too, so tried loading it from the desktop. That only partly worked, and I get the same error messages about content.
I tried to use the Download Assistant for two days straight. It gets somewhere between 3 and 15 GB and then I get a ‘failed’ message.
It also tries to put it in my ‘download’ area, and I don’t know where to move it to if it ever finishes.
Totally frustrating. I’ll probably open a ticket with Steinberg, but I don’t hold out much hope. It might work better if the the giant dl file could be broken up into smaller sections, and if there were some kind of directions on what to do with the downloads.
