I recently purchased the Mamba Elite, and I just started having this issue, whenever I change my profiles at the bottom of the mouse, the led does not change colors from white to red to green, etc. I installed m y mouse drivers and installed synapse and reinstalled it. and before i downloaded synapse i was able to change profiles with the led switching colors, but after i downloaded synapse, the color staid a solid white, and would not change colors when I would change the profiles.
