I have the same problem, I downloaded the hash file but I am confused as to whether or no I should put it somewhere specific? The Blockland foldr in 'Documents' was created for me, but no 'Add-Ons' folder was created so I made one myself and added the hash to it, that didn't work. I also extracted the files in the hash and repackaged them into 'Brick_V15.zip' that did not work either. Log is below, it's mostly a stuffcrap of spam about how I couldn't download blobs because no connection to the server was ever established.
