After I downloaded the 1.6 patch for Minecraft I made a version in the launcher for 1.5.2 along with the default (1.6) however when I downloaded the new launcher the game glitched. so, I backed up my saves and did a clean install of minecraft. I put my saved back in the saves folder. however my problem lies with optifine, in the Jar file for the 1.5.2 version I placed the mod however it does not work, it is also the latest version. here is the file directory
C:\Users\Userneme\AppData\Roaming\.minecraft\versions\1.5.2\1.5.2
C:\Users\Userneme\AppData\Roaming\.minecraft\versions\1.5.2\1.5.2
