Common problems and how to fix them

Work through this before posting. If none of it helps, reply with what you tried.
"Invalid username or password"
Almost always one of two things:
Nothing happens when you double-click the jar, or it flashes and closes. Run it from a terminal instead so you can see the error:
If it says java: command not found, you do not have Java. Install Temurin (adoptium.net) or your platform's OpenJDK build — version 11 or newer.
If it starts with an UnsupportedClassVersionError, your Java is too old. Same fix.
It hangs on the loading bar
First launch downloads roughly 126 MB of game data. On a slow connection this takes a while and the bar can look stuck. Give it several minutes before deciding something is wrong. It only happens once.
"Error connecting to server"
Old artwork, wrong logo, missing sprites: download the client again. Updates ship inside the jar and in the cache, and an old copy will show you old art.
My purchase has not arrived
Type ::claim in game — that pulls down anything queued for you. If it is still missing, post here with your order reference and the exact name you typed at checkout.
I have been banned and I think it is wrong
Post here with your account name and what you believe happened. Stick to the facts.
Still stuck?
Reply with: your operating system, your Java version (java -version), what you did, and what it said. Screenshots help. "It doesn't work" does not give anyone anything to go on.
"Invalid username or password"
Almost always one of two things:
- You have not registered. The client has no sign-up. Your account is made on this forum, and that username and password are your game login. If you never registered, there is nothing to log into.
- Typo. Try logging into the forum with the same details. If that works and the game does not, post here.

"Error connecting to server"
- Check the site — if the world is down it will be down for everyone.
- Re-download the client. If the server has been updated, an old jar can fail to connect.
- If you are on a work or school network, the game port may be blocked. Try another network.
