Quote from Prince_Deity
Why do you miss the old launcher? You spend only seconds on the launcher, so it doesn't affect gameplay, and you need the new launcher to be able to play any version from 1.6 and on. Also, when did the old one start giving you a black screen? Were you trying to play an unsupported version on it?
I was just trying to put a mod on it and all the sudden, Boom! Black screen! i cleared the .minecraft but still nothing it also affects all of the other java things (except the new launcher)
