Help: Material Editor Slot showing Black

how to solve this kind of problem..anyone..?tia

Check your render engine. It is showing in black because the material is not compatible with your render engine assigned.

thanks for the reply..but i didnt yet add any material in the slot..thats the view of my material editor everytime i open max..

what is your assigned render engine? you may want to change your UI in accordance to your preferred render engine so that whenever you start your Max your Material Slots are all working with your render engine

i try to switch my render engine from scanline, vray and mental ray...and try to play also in UI but i get same result evrtime i start max...i think this thing happen when i installed the SP2 for my max 64 bit...
