Packaging Error.
The file should be a .zip eg:
Player_(name).zip
for a weapon it would be:
Weapon_(weaponname).zip
You must have inside a file -
--------------------------------------
description.txt
Title: (title)
Author: (Your name)
(description)
server.cs
exec("./Player_(name).cs");
namecheck.txt
Player_(name)
(yourplayertypefile).cs
------------------------------------------------
Your file must be in the right location! MAKE SURE IT IS
C:\Documents and Settings\(yourname)\My Documents\Blockland\Add-Ons
or just go to "My Computer" and to the right you should find "My Documents" then blockland/add-ons.
I hope this helped.
