Hello everyone, on December 18th I received an email to update SkyMaxx Pro Version 4 Upgrade! As of this date my products that was purchased in x-aviation: SkyMaxx Pro v3, Real Weather Connector, IXEG 737 Classic, SoundMaxx, UrbanMaxx V2 3D. Activation Failed: All license slots used, I already sent 14 tickets for x-aviation but you do not want to respond and I do not know what I can do ???? I was hoping for some help, some tip thanks
