Note in the screenshots that cloop has been upgraded to 4.0 GB and a second cloop added? This accounts for the ability to load to 4.0 GB. If you can't decompress 4GB file with cloop because cloop is too small (say normal CD size 2GB) would make sense.

I have tried bittorrent via the links and have received error messages on each attempt, one occurred after 1GB download saying I had two instances of the file.

I have bittorrent 4.2.1-2 installed.

Cannot download without errors.
