I dont know whta else to do, Can someone Pleas help me, Any help is apprecitated.
PS i visited Lyons site, and nothing works still

As instructed in the FAQ: Re-run Adobe Gamma, and use a different profile for the starting point.

This may be too simple an answer for your problem but make sure you have black for your default in the color palette. The frame should be around the black in both places, the default picker and the color palette,the one with the color bars.
