Voronoi shattering tools by Phymec

I got a new build and it works very good but for these seams on all my fractured objects. Now I cant bet the browse to come up for insert image here…well I get seams, The faces on all fractures are not touching, very small gaps.

Hello!
Sorry for being noob again, i watched videos over 45 minutes, but i still don’t know how to use this, how to start it, how to install.
Thanks.
