Press Access key and enter the key you were given, exactly as written (upper or lower case and spaces do not matter). Keys can be withdrawn; if yours was, ask the developer for a new one.
Check your internet connection and press Check again. If it keeps failing, the server may be restarting: try again a little later. A version you already installed can still be played.
Nothing you already had was changed. Press Check again, then Update (or Install).
The launcher refused update information that did not come from the developer unchanged. Do not try to get around it; report it with the time it happened.
Press Repair: the launcher checks every installed file and downloads the version again if any is missing or damaged. Make sure your graphics driver is up to date (the game needs Vulkan). If a new version misbehaves, Roll back returns you to the one you had before.
The launcher is not code-signed yet, so Windows does not know its publisher. Choose More info, then Run anyway. Download it only from this website.
Allow it on private and public networks; online play needs it.
Press Uninstall in the launcher. It removes the game and the launcher from the folder you unzipped, and nothing else. Your saved games and settings are removed only if you tick that box.
Known issues in the test versions are listed in each version's patch notes.
a standing list of known issues will be kept here.
Tell the developer what happened, what you expected, the time it happened, the version the launcher shows, and a screenshot if you can.
the address or form for reports has not been chosen yet; until then, tell the developer directly.
