Hi toyota_kid_85
Please clear your browser's cache (
https://www.flyordie.com/games/help/support/clearcache.html
) and start the game from FlyOrDie's Homepage.

If the game recently updated its files or security certificates, your browser might still be trying to use the old cached version. That’s why you’re seeing errors like “certificate not valid” or the game not loading at all. By clearing the cache, you force the browser to throw away those old files and fetch fresh ones directly from the game’s servers.
Kind regards,
John
