Trying to play Blockland with some friends, and it was also working perfectly fine yesterday. I was trying to launch it, and got this:

I've tried to delete my Add-Ons folder so it could force re-write the required Add-Ons once more, but that failed.
If anyone has tips other than re-installing the entirety of Blockland, please help me out. It's more than likely something on Blocklands end that Badspot needs to fix.
