My Big Dig is crashing for no reason. I was playing it and got off for a little while and when i got back on it was saying that big dig has crashed before i was able to play it. I opened the Big Dig modpack and it pulled up minecraft and set up my enviroment but then it pulled up a screen saying that minecraft was unable to open and also told me to post a report with it but i can't post it. I also tried re-installing java and the technic laucher and don't know what to d about it. Please help!
