Game crashes upon attempting to launch singleplayer game

[Planr]

Whenever I try to startup Starmade Singleplayer, I get this error:

Now I can play multiplayer just fine, but whenever I try to play singleplayer, I get this crash upon launching the singleplayer game. This didn't happen the last time I played Starmade two weeks ago.

I'm getting the feeling this has to do with some sort of outdated file in my game folder, or something like that. If anyone knows what might be wrong, please tell me.

Things I've tried already, none of which has had an effect:
-Restarted the computer
-Restarted the game
-Terminated the java.exe in my computer's "processes" list

you should try to remove the shown .lck file.

This should unlock the db, and let the startup recatch the SQL data.

In case nothing helps, and you have a backup of your universe, try using 'reset universe' and try again.
