Upgrade OA from dvd to Brittish Exp. on Steam?

[sigge88b 10]

As my unclear headline says. Is it possible for me, who have bought the previous versions on dvd disks to now buy the new Brittish expansion through steam?

Or will I have to buy it on dvd?

AFAIK you will have to buy it from another source, but it isn't sold on DVD.

Arma 2: British Armed Forces

Yeah, Steam only allows you to buy the expansion if you own OA on Steam. I have a Steam Arma2 install with a DVD copy of OA merged in, but since OA isn't bought from Steam I can't buy BAF from it either.
