I have been playing Minecraft version 1.6.2 with 2 mods:

SinglePlayerCommands-MC1.6.2\_V4.9  
OptiFine\_1.6.2\_HD\_B4

…since last August. I last played on 5/17 with out a problem, but a few days ago I went back and it keeps crashing without getting to the menu.

I can play the unmodified 1.6.2, but I really need OptiFine to make it work on this old computer. Nothing has changed on the computer.

Here is the crash report I got:

Have you tried asking on the Minecraft forums? Minecraft-related threads seem to die a sad and lonely death here.

I was hoping someone here would read & understand the crash report and know what happened without me getting called stupid by a 13 year old. 😉
