stuck in Logo screen

Does it happen only since the latest update? Any errorlog created?

It may be related to the focus: If the game is not focussed, it pauses. If you play in window mode, try clicking the games window again so that it gains the focus. Otherwise, when playing in fullscreen, try alt-tabbing to desktop and then return to the game.

But we're also working on a small bugfix (fixing a problem when loading old worlds sometimes), it will be released within the next 1-2 hours. We will change some stuff related to the focus, maybe that fixes your problem

That's spooky... You could try opening the config.properties file in your game directory and change the flag "game_pause_on_lost_focus" to false. Then start the game and check out if it still hangs.

If that does not work, it might be helpful when you set the flag "game_debug_console" to true, then start the game and when it stucks, either copy the content of the debug window or shutdown the game and upload the latest log file from the "Logs" directory (it will only be created once you have shutdown the game).

That's really spooky Especially since this error only occured after the latest update. According to the log, the game either finds no soundfiles, some textures are missing, or it runs out of memory. The latest one could only happen if you made any changes to your system/java, but then an errordialog should be shown. But the missing sounds/textures scenario also makes no sense, since in this case the launcher would also bring up a dialog saying that gamefiles are corrputed or missing.

Anyway, we're really sorry for this inconvenience!

One last things you could try: Open your config file and set the flags game_threaded_loading and game_use_mxbean to false. Then start the game and if the error still persists, please provide us the logfile again.

Thanks for the errorlog! It seems that some gamefiles are out of date. Usually this should not happen. Please go to your game directory, then to "data", then "assets". Delete your "materials.jar" file and then start the game. Now the launcher will tell you that some gamefiles are corrupted, simply click yes to redownload the missing files.

If the error is fixed then, you can set 'game_threaded_loading' in your config to true again. This speeds up the startup time of the game.

This may be related to an old bug from a former version, when loading the game without "threaded_loading" enabled. That's weird indeed, since deleting the materials.jar in the previous step should have caused the launcher to redownload all differing files.
Please try deleting the files "commons.jar", "concept-core.jar" and "server.jar" manually in your data folder and set the flag "game_threaded_loading" in the config to true, then start the game again. Please tell me if that works now.

Great, glad to hear that!
