MadLocustRising1 08:27, 3 March 2013 (UTC) the newest FTB update doesnt work for me or my 2 friends, and i think its the same problem. we have NO extra mods installed. ONLY the pack as it comes. our computers are more than good enough to run this. please help us... this is getting annoying. i downloaded and installed like im supposed to. everything is standard as the pack's come. obviously something is wrong with your update on our computers dear FTB: please help...
