You can use the “Direct Download” link under the BlastClient (by BlasterBuilder, game version 1.10.64.1) link on the downloads page. If that doesn’t work and you can’t torrent Nexus2, I can also give you a direct link to the blastclient in a .7z format. I managed to compress it to around 2.5 GB, which should be small enough to download continuously at a medmium to high speed without corrupting it.
