Just followed the instructions step by step on LEDBLINKY site and it worked first time just noticed this from the instructions, this is probably the answer to my question even though you said you already tried. The LEDBlinky plug-in should not be used in conjunction with any other MaLa, AtomicFE, or GameEx plug-in that controls the listed LED controllers. If you have installed another LED plug-in, it should be disabled or removed from the plugins folder. The LEDBlinky plug-in should not be used in conjunction with any native front-end feature that controls the listed LED controllers. Please disable any MaLa, AtomicFE, or GameEx LED features.
