FSD International aircraft woes: incorrect OAT.

I purchased 3 of the FSD aircraft: the Piper Seneca V, the Aerostar 177 and the Commander 115TC v1.They all display the Outside Air Temperature as 0C on the ground with the default KSEA situation of Clear Skies. Switching to any other aircraft, including the default Cessna 172, they all display correctly 15C, but not the FSD aircraft! :( If anyone else here has a recent build of these aircraft, or better a recent install using the latest installers from FSD, could you check if you see this problem, please?I wrote on their forum, specifically as the Aerostar 700 has another problem with the Pressurization system and I wrote directly to their Support. Until now their answer is inconclusive.I was just wondering if anyone else had the same problem. I've tested them in Windows XP and Windows 7 32bit, and in the process run out of activations! :( My Win XP is a recent install and FS9.1 is installed without any other addons, except for the FSD aircraft.Many thanks! :(
