So I've tried this before with several mods in the modpacks.. Updating the smaller mods that is placed in them :IE: Optifine. I will place the files into the jar folder but as soon as I load up the modpack again nothing is updated. The main mod I want to update is Pixelmon. All parts of that mod that was posted has been updated from 1.5.1 to 1.6.2. Is there another way to update the mods or maybe something I'm doing wrong? Anything would help. Thank you.

Running with minecraft 1.5.1

Same error comes up in single player or multiplayer. Can not make items like refined iron, iron furnaces, or even tree taps. Battle axes, hammers, and quartz tools are possible though. This does not get fixed even if server, game, or computer gets restarted. When playing in multiplayer it is just opened to LAN, not on a offsite server. Error Messages: None. Error Log: None
