Math font that works with mathmagic

Hello.

I'm new to InDesign and i try to use to write a scientific book that has a lot of equations and math formulas. 

I see a book that was written with InDesign i asked the author about which plugins he used to wrote it , he responded saying that he used mathmagic.

I purchased mathmagic add it to InDesign but my equations look very ugly, i tried to change font but tha mathmagic keeps saying that he didn't find the postscript for the font .... i can only use tha mathmagic fonts and all if them produce a very ugly equations .

But in the book i mentioned earlier the equations look very good.

My question is which font they are using based on the screenshot i linked to my post?.  and what is the best practice to use InDesign with mathmagic?.

Thanks in advance
