Hi, I have a kind of similar problem on log in.
I get a "Authorization Failed, The following DLCs are not authorized and will be disabled. Christen Eagle II AI, F14B AI, Mig 2Bs AI"
Interestingly appears to be all AI aircraft.
I have not purchased any of the above so totally flumuxed! This all happened after installing Skate Zilla GUI. There must be a file somewhere that requests those files on login but be blowed if i can find it.
Have tried all the above fixes to no avail. Game still OK, just annoying.
Any ideas?
