I used a batch file, but it did the same thing.
STEP BY STEP DIRECTIONS!
BTW: TURN ON FILE EXTENSIONS IF YOU HAVEN'T ALREADY!
If you don't know how, die. It will do it itself... lolz jk, Hint Windows Explorer Window>Tools>Folder options> View Tab>Uncheck Hide extensions for known file types.
1. Extract the files into [INSTALLDIR]
2. in your INSTALLDIR, create a new text file and call it Blockland with Editor.bat
3. Right click Blockland with Editor.bat and click edit
4. In the window, type in "blockland.exe -mod editor"
OR
1. Right click the shortcut that Blockland Installation makes to start BL
2. Under "Target:" At the very end, add -mod editor
If it doesn't work, you fail. You don't deserve to be able to access the BL Mission Editor.
