For some reason, any mod/modpack that require forge don't work. I click on play and it just opens Minecraft for a second and then closes it. I don't even see the Mojang Screen. I'm sure that it's not because I couldn't install forge properly, any modpack that requires forge doesn't work either. I have tried FTB modpacks, ATLauncher modpacks and my own modpack. Forge works if the Minecraft version is past 1.6, I can play FTB 1.5.2 for example.
People said that I needed a 64x computer and Java but I already do, I have the latest version of Java (51) installed and it's 64x. I'm also sure that I have a 64x computer.
Here's the ForgeModloader-client-0 from FTB Direwolf20 1.6.4, I hope it helps!
Thanks!
