Hi, I bought a gold MSI Loot Box that had gaming mouse M99, mousepad and a plushy toy. I cannot register the mouse. I saw some P/N number that it had and below it was the full number, whenever I type it, it say Product S/N Error. Whenever I type the loot box number it says this page is only for registering products. Do anyone knows where the heck is the number I need for the mouse???
