FSX - Aerosoft - Mallorca X

So it seems aerosoft's communication is a bit misleading here. For me, "compatible" means that I can the software without restrictions and fully functional in P3D v4. I mean, where's the line here? You can't say it will install in P3Dv4 but it doesn't work with the features of v4. That's not what compatible means IMHO.
