In normal minecraft launcher I select profile with forge (1.6.4) and press play. Than launcher closes and does not open anything. (It also do same in magic launcher and technic launcher... but it does not belong to this forum). I can not find any error log, I searched in .minecraft/logs but only found latest. I tryed to delete .minecraft and install everything again. I have empty mods folder. It also worked before... Please help.
Sorry for my english.
