Mods loaded find, The base Minecraft client itself failed. Would you mind posting your OS, Java Version, and Launcher version?

[DefPdeW]

OS: Windows Vista 32 bit Service Pack 2

Java 7 update 10

.exe technic launcher, version 1.0.4.3

Vanilla minecraft works fine, Yogbox and Tekkit Classic as well, but Tekkit Lite and Voltz crash.
