I purchased a StarCraft Anthology from Blizzard.com, and it is a digital purchase?

I spent 14 bucks getting a game I have not played in 7 years, felt like going back to the day. And they don’t have a massive 1.2 gig file for me to down load, they installed a P2P program and the download rates are horrible. Blizzard only lets me DL from them at around 20.kb and the P2P members at about 2.kb apiece. give or take 3 Peers, I am looking at DL’ing a 1.2gig file at 25–30kbps. What the fuck is that all about, My DL rate is ussually about 100kbps, and I am on a cellular wireless 3G network. I had to drop all my fire walls and get into my server and allow Ports 6889–6999 that is a thousand open ports so that I could even get 28kbps, when I started my download rate was 2–4kbps, WHAT GIVES why cant they allow me to do a dump one file download. Is there anyone that can HELP me with some Techno Jargon to speed this stuff up with out ripping my firewalls to pieces?
