I uninstalled the previous version of blockland as it was giving me trouble, and installed v18. I got ingame, and the first server I connected to was badspot's, which was fine. Then I tried lord tony's which was fine, but non others would work. I also can't change the folder permissions, because it's a virtual drive. And yes I'm running the executable.
Want me to make a video of what happens when I try to change the folder to read and write?
