Okay, so I made my mom a modpack to play on at home since she doesn't have internet. I have internet at my apartment, so she came to me so I could download everything for her and put it together. It worked perfectly here, but when she got home she sent me a text saying that it wouldn't even open now. Everything had already been installed and had been played on for a few hours. She says it won't even open up the regular launcher now. It doesn't even show up in Task Manager. Any ideas as to what might be causing this? Does forge HAVE to be connected to internet at every launch now?
