I dont get how the hell people get these errors...I mean seriously..
Ok first go to options and go to network. Check off download sounds, music, and textures. Next, go to my documents/Blockland/config/client/prefs.csReplace the 0 with 1 to everything that has to do with downloading. Hope that helps.
Do what scratch said :)
Try deleting your cache.db (cache database) it is located inside your blockland folder. Deleting this will make the game reload some server files but will not mess with your game. Although I would make a backup of it before deleting it.
Will it delete my saves
Just change the all circled numbers to 1.
