you have an addon with syntax errors:
Client checking Add-On: Client_GreetMsg
Loading Add-On: Client_GreetMsg (CRC:-666099214)
Add-Ons/Client_GreetMsg/Client_GreetMsg/client.cs Line: 29 - Syntax error.
>>> Some error context, with ## on sides of error halt:
activatepackage(ChatParent);
function Greet(%name)
{^if($Greeter !$= 0)
..............
suggest you disable that addon and try again. Also, sometimes it helps to disable any addons you dont use, then blockland starts faster cause theres less addons to load.
I also see this:
Error opening zip (Add-Ons/Colorset_Default.zip)
Check to see if that zip file still works. (can you open it?). Also try getting a fresh copy of that file from some place else.
Or try re-installing blockland
