ok wel i have alway had it in disabled but just to shw you here it is Uncaught exception from thread:Thread[LWJGL Renderer Thread,5,main]
java.lang.UnsupportedOperationException: GLSL and OpenGL2 is required for the LWJGL renderer!

See... this error is not the same as the original one. The original one is because AA was selected and this one is because your card is too old for OpenGL2 or it has old drivers that don't support OpenGL2. Did you get these errors on the same system? Maybe it's just confused.
By any chance is it a laptop with two graphics cards in it? Some laptops have a lower power intel GPU and a higher power nVidia or something. Can you tell me more about your system and your graphics card?
