Been away from FSX for a while and now it seems people are using REX Essentials Overdrive +. I have Rex 2, which has served me brilliantly up until now. The REX forum seems to be down for maintenance and I can't work out how to get from REX 2 to the latest version. Do I have to buy REX Essentials Overdrive + from scratch or is there some kind of upgrade path from REX 2?
Many thanks.
