A pattern appears in smoke renders: How to fix?

Ok this may be a dumb question... Where are the help files? I looked on the website (post login area) and only see tutorial videos and the plugin. And as for on my computer when i download the plugin and install it i look in the 3dsmax/plugins/afterworks/ and I don't see any help files there either. I know i am probably missing something, but i can't think of where they are.
