Launcher Update?

Well I saw we needed to update my Minecraft Launcher, so of course, I did. When it finally downloaded, It still wouldnt let me go on 1.8.1, 1.8, 1.7+ with Modded Forge and Optifine (not in the same type) Everytime I clicked one of them and pressed Play, it didnt log me on to my server. When I got on 1.8, ALL my servers were gone, my worlds still there. This is URGENT and I need a helper A.S.A.P
