Issue: When logging in, you get the error message: "Version check rejected by lobby server"
Possible cause: Client needs to be updated
Solution: First click on "Retry". If that does not work, click on "Update". This will download the Trove Alpha Installer, run the file it downloads. If it fails to update, go to your Trion account and download the alpha client again, then re-install it (try this link: https://pjalpha.trionworlds.com/account/profile/manage-game.action )
