Hey guys, so it's been a while since I've played Minecraft, and I wanted to start back up again, so I downloaded a map from the cube, put it in the saves folder, but no matter what version I'm using or which of my worlds are opening, my screen will freeze for a few seconds, then crash and have a Runtime error that says r6025 pure vital function call. I've restarted my computer, and even deleted and reset everything in my .minecraft folder, and I still can't go on any maps. Any help would be appreciated!
