Troubleshooting

I Cannot Log In As A Registered User

Check:

• account id,
• password,
• whether first login asks for password confirmation.

If the password is forgotten, contact course staff or the system owner.

The Room Link Shows No Games

Possible reasons:

• the moderator has not started a game,
• the moderator started the game in a different room,
• the game was stopped,
• the browser has not refreshed the room list yet.

Wait a few seconds or reload the room page. If the game still does not appear, ask the moderator to confirm the selected room.

A Player Name Is Already Taken

The name is probably still connected in another tab or browser.

Use a different name, close the duplicate tab, or wait until the previous connection is gone. If a PIN was used, reconnect with the same PIN.

The Game Is Waiting

Possible reasons:

• not enough players have joined,
• another player must act,
• a timed stage is running,
• the server is preparing the next state,
• the connection was interrupted.

For fixed-player games, waiting before the session fills is normal. The first players should not see the game state early.

I Joined The Wrong Game

Return to the room page and join the correct open game. If the wrong game is the only visible game, ask the moderator which room link to use.

A Decision Does Not Advance The Game

Check:

• required fields are filled,
• dropdowns are not left unselected,
• the clicked control is the active player's control,
• the page did not show an error or warning,
• another player is not still expected to act.

If the decision was accepted but nothing changes, the game may be waiting for another player or a timed stage.

Join Or Open Test Does Not Open A New Tab

Browser tab behavior is controlled by the browser.

Try:

• allowing popups for the site,
• using Ctrl click or Cmd click,
• opening the room link in a new tab manually.

Upload Fails

Check:

• the file is .mgd or XML,
• it is a valid ComLabGames game definition,
• the game type is currently supported,
• duplicate overwrite was confirmed if prompted.

Start Is Rejected

The same uploaded game may already be open in the selected room.

Stop the existing game, use another room, or choose another game.

Demo And Test Behave Differently

This is expected.

Demo uses one tab and switches between players. Test uses separate player tabs and is closer to a real classroom run.

The Screen Looks Different From This Guide

The application is still changing. Follow the live screen first. If the difference affects classroom use, report it so the guide can be updated.
