Good Day,
I downloaded the latest forge, 7.7.2.679 and installed it along with my mods. Everything works fine when I'm connected to the internet.
Unfortunately, I don't have internet at home (yes I know but I'm pretty poor) when I tried to start minecraft at home or offline at the library minecraft starts up but then when I log in and it tries to do the "FML is setting up your minecraft enviroment", it starts trying to download file scala-library.jar and then I get the message:
There was a fatal error starting up minecraft and FML. It states minecraft cannot launch in it's current configuration and then stops.
I didn't have this problem with 1.4.7 but I just recently upgraded minecraft to 1.5.1.
Again it only happens when I'm offline. When I'm online it loads fine. I also tried the recommended build 7.7.2.662 and build 7.7.2.678 thinking maybe it was just a 679 problem but I get the same error.
Thank you for your time and effort on making minecraft the game it is.
