Fume fx. help needed. asap. please


I am new to CG Society so I am sorry if I am posting this in the wrong forum. I needed help with fumefx. I am trying to render an explosion on fumefx but I keep getting these noise like thing in my renders and as well as in my preview. I couldn’t find out the issue. It’s a really strange issue. I’ve found everything on the net but not a single one has addressed this issue. I am learning through an academy and they too couldn’t figure out the issue. I’ve tried re-installing 3DS max, fumefx. Tried different versions for both but the problem still persists. Even tried it on different pc. I am really going helpless. Please help me. Please.
