btw... if You didn't installed new os run epiLight once again and when error will appears click on a Details and take a screen for me

ah and one thing... please use "10*Movie smooth+Fast scene" mode!
Fast scene reaction should be 128. If value it's lower than it is more aggresive changing colors.
Smooth 3x at color means to do not change smooth color for next 10 _frame_s, but to smooth for only 3 _frame_s when colors different is smaller than 96.
Screen divide means for how many pixels in X and Y screen should be divided. So if there is a 64 it means to grab 64*64 pixels which is 4096 pixels. It is really a lot and enough ... could be used only on a fast CPU.
Offset multilpier - You shouldn't use it - 0 value is ok.
Capture screen every X cycles will also make ambilight more smooth especially when screen capture operations is really slow (do not set it to more than 16)
Color increase You can set for a 20 and Inc. delay 15. At the begining color increase will be always 10 and will increase (+1) every 15 (Inc. delay value) cycles - only when color difference is not more than fast scene reaction / 3. If different is bigger than color increasion will be decreased. On a Fast scene reaction it is automatily reseting to 10.
Expand individually You can use when You are watching movies at day where is very light in Your room. At night You should always choose No expand.
BTW: Update Your GPU (graphics card) and MOBO (chipsets, and etc) drivers.
