Here's what I ended up doing.. did end up at a comp with cable, installed DCS World 1.2.8, zipped the install, got caught up in another project. Came back home, but forgot the USB stick........ so, I fed 20$ more into cable bill so I would have another 2 gigs for downloading update for my original DCS World 1.2.7
I'm now on 1.2.8 beta, but a few bucks shorter.
Next time I'll just carry the comp with me. A lot less time and cheaper that way. (and I don't have to remember to bring the USB stick back with me)
Thanks for input!
