Hey guys, new here, and I've been playing Tekkit for about a week or so. But just today, I wanted to play Tekkit Classic. I hit the big play button, the progress bar fills with words, aaaaand, kicks me back to the start. No error message. Nothing. I will add a video of exactly what is happening. Thanks, Ameji EDIT: Well I fooled with things and now it wants to restart Tekkit Classic. The menu only lets me choose Play Offline, and there is an error message. My recording software failed me... and while I do have a better one that one will take a LOOOONG time and I want an answer asap... please help
