Sometimes some addons kill you for some reason.
A console.log might help, so post one when you crash.
In other words, you may have an add-on that is conflicting with one that the server has. Also as Deriboy said, post your console.log file found in your Blockland folder.
Windows XP: C:\Program Files\Blockland
Vista: C:\Blockland
Before you post the console log, go into a server that causes you to crash, open your console (the "~" key above "Tab" on your keyboard), and type:
trace(1);then hit Enter. Your console might seem like it's going crazy, but that's normal. Just wait for the crash, then access your console log and post it here (as an attachment please, do not copy and paste).
