Everything looks like it loads up ok and I already use forge for other things but comes alive just goes to a white screen and no further. Using 1.8 for MCA

You'd need to post a client log for further assistance.

Was this what you were after

it happens to me too. In my case it's because i don't have RadixCore

Yeah to mee too, after loading the screen of the main menu (the single...multiplayer buttons) is all white with music playing in the background. It not like it crashes minecraft...i dont see any crash report. To me it fixes itself if I press ESC key, then I can see the main menu. odd bug.

Make sure you have all MCA's dependencies, use the recommended version of Forge, etc. I'm unable to reproduce this problem.
