So TruBluRage tells me to install Blockland in a seperate directory, so I do.
So, I run the alternate one, and I'm in demo, and I can start single player servers just fine.
So, I get out of that one, and start Blockland from where I usually do. I join a server, I get finished downloading the file manifest, but it results in the SAME FRICKING ERROR.
Then there's an ingame window I see, and it says something similar to:
"this means the game will almost certainly not work."
Really?
I'm quite angered now.
