I bought GSX but I can use it only in trial mode.
I insert serial and it says that GSX is activated and I can use backup reg key for future reinstallations on this pc but when I go to open gsx menu pressing ctrl + f12 it says to warp in trial mode airports.
I turned off Windows firewall and I haven't any antivirus installed because i formatted since 1 week.
My friends when they start fsx it says something like "gsx is installed but not activated, would you like to activate it now?" but i haven't any message on startup
