Crash problem since July update

[Ripp]

I have read the other similar posts but none seem to clear this up for me. The game has done the same thing since the last update. I have tried both 64 and 32 bit Java, checked my drivers for updates and done several reinstalls of the game. It crashes at 100% loaded. File with screenshot attached below featuring error message (hopefully). Any advice would be appreciated.

ACER Aspire G7200
AMD Phenom 9850 quad-core
64 bit operating system
Windows Vista Home Premium 64 bit.

It looks like your machine came with a Radeon HD4850?
Have you updated Catalyst? The AMD/ATI driver pack? Your machine should support OpenGL 2.1 like a dream. Though seeing Vista in use worries me for some reason I can't recall. You can check in some of the minecraft forums. They might have seen this already and both MC and SM run in a JVM sandbox so some trouble shooting steps are incredibly similar.
