If you are getting stuck on the verifying user name and password screen:
Try opening up your firewall settings and manually adding all of the exes that run, not just the update launcher.
If you're having issues moving your windows on a second monitor:
Try using windows key + shift + arrow keys to move those windows to the first monitor then you can drag and drop them where you want them to be on the second monitor. I realize this is not the fix, but it's a workaround that will let you keep playing.
If you get odd errors you can always try repairing the game with a fresh installer from the realmserver website. If that doesn't work you can try uninstalling and completely re-installing it. Just keep in mind that you may have to re-add the exe files to your firewall's allowed applications again.
If your account gets ghosted (stays logged in after you crash) you can use the /reset toonname command with another account that's linked to your web account. If you have not done so already link all of your accounts to your web account so you can unghost your accounts if they get ghosted.
If you have any other issues trying to get the realm to run (and there are many) just private message me on discord. (I'm Driftwood Gaming) by right clicking my name on discord and clicking message. Good luck and I hope to see you in game. :swords up:
