Hi, recently I tried to do a flight. However I encountered problems with GSX activation. The addon manager says it's not registered and everytime I register my serial (I did not copy paste) the result is still the same: the addon manager saying it's not registered. I reinstalled GSX, and this time I'm greeted with the Soraco popup. Both online and offline activation failed, saying my registration key was invalid. Out of curiosity I tried registering via the addon manager again, and this time it did register. However, when I bring out the GSX popup, it says I'm in trial mode. Please help, I bought GSX way back in 2016 and never once had an installation problem.
For reference, I did try installing with antivirus and firewall disabled.
