Could someone please explain what the general guide to solving GameGuard issues is? I've been troubleshooting GameGuard for a while now but it's not really helping. I'm on Windows 10, 64-bit. I've been told to try disabling my firewalls, or whitelist the GameGuard folder (doesn't seem like I can do that with my antivirus program, it only whitelists exe/dll/jar files), or re-verify the game local files on Steam.
I don't even know what my error code is. It's just been stuck in the 'Retry' phase over and over again. I can only guess this happens when GameGuard is updating but it keeps failing.
This is the second time it's happened in the past few weeks and last time I had to re-install PSO2NGS in its entirety over the stretch of 8+ hours. Steam just decided right now to reinstall the game, 82 gigs worth.
