I have BL version 14 and whenever I try to host my own server the game crashes. How can I fix it so I can host a server?
Make sure no-other programs is working so you get max power to the game, and don't play in fullscreen.
Run blockland in bad quality, might help.
Also consider buying a newer computer or upgrade your old one.
If your playing on your daddy's, its no use. Your father don't care having a new computer, because he only uses writing programs and mail.
Good luck
