Are you missing Blockland.exe or BlocklandLauncher.exe or what? Try going here (it's an official download link, don't worry) and once you download it, copy BlocklandLauncher.exe to some directory and run it. It should download Blockland.exe or anything you are missing. It's also a launcher for the game if you don't have it.http://blockland.us/files/BlocklandPortable.zip
it is there and both blockland starters are gone
