Suddenly all luts in 'motionvfx mlut plugin' disappeared ......

Facing a weird problem with mLUT plugin in FCPx , yesterday suddenly all LUTs that I had categorised and favouritized have suddenly disappeared when I open mLUT plugin now , it is blank as if it is newly installed, not understanding what must have gone wrong.... it was lot of hard work and several project files might be rendered incomplete without colour correction..... It's with Sierra but was successfully working for months till yesterday nothing new was installed , just that I tried to make a custom LUT in photoshop and tried to load it , after which this might have happened...... also I am seeing in the project, clips have the effect with chosen LUT , but on opening the plugin again it is blank not showing any lut, not even the chosen one...... is it possible I might have pressed some option in the plugin by mistake ? Need your help.
