plantninja I have to agree with midorijin, think you may want to use a download manager. This sounds like an issue with your ISP, whether it's just flash outages that are long enough to cause the download to time out, or whether it's intentional throttling on their part. I've downloaded that specific scene (both the full 6k and the original 6k) without issue.
p.s. whenever you're able to download it...well worth it haha. Great scene.
