Minecraft Forums

I'm sorda new to this stuff so i have no idea what happened.
Basically, after i updated minecraft today, all my mods got deleted and i had to put them back in my minecraft folder.
The mods i put in were
-Optifine Ultra
-Optifine Light
-Optifine Standard
-Better Sprinting.

When i finished and opened minecraft, this popped up:
Minecraft has crashed!

Anyone know what i can do?
Thanks

the mods u put in were probably not for 1.5.2. to fix your minecraft, start up the launcher. in the login screen, click options, then click force update, then login.
