Question here, updates have been made, FS is current, and afterwards, I have no access to the latest Military aircraft addon, or the ability to locate several aircraft which were earlier added, and now are no longer there. The latest addon for the ‘Top Gun’ is not available to be used either. How do I recover these missing options from the game ??
I had a similar issue. Go to content manager and reinstall. (You may have to remove first).
Make sure your F18 is installed also.
I had a similar, albeit breif, issue - all greyed out whilst everything else was available until I restarted the game
