It's just like the title says, folks. @@
I've tried both downloads several times. The high resolution one stops at 91%, which is an infuriating, hope shattering number to stop at, and the normal one stops at 34%. XD;
No error messages, no 'elapsed time: 100020 hours', just 'calculating time remaining...' and the regular download screen.

I've tried stopping the download, saving it to the desktop and rebooting to try again, but that didn't work.
I'm beginning to think I'm just not meant to play this game... XD;
I run on Windows Vista, if helps.
