Ok, So on my custom pack, I got everything right but when I launch it it opens the forge window, goes black for a second, then gets stuck on the mojang screen. I can't even figure out if this is normal or not, but it dosen't go to the title screen. Maybe it's the size of my modpack or it's just that it gets stuck. I just don't know. I have some screen shots for proof so you can see

Then It dosen't go past the mojang screen
If some one can tell me what exactly is happening, let me know.
