Alright, so the Midas Program seems to work fine. I load the Tekkit Classic World, I selected the patch file, I ran the program, and the world was converted. Next, I moved the world file to my Tekkit Lite world folder. But then, when I opened Tekkit Lite and tried to open the newly converted save file, it says "Loading World | Building Terrain" like usual, but then it flashes back to the title screen, and then to just a dirt texture background, and then I get an error message saying "Disconnected by Server | Server Closed" and a back to the title screen button. My original world was not a multiplayer server. Can anyone help?
