Downloaded CC gives pixels, help?

Hi all.

I downloaded some beautiful make-up from GOPPOLSME. I have this issue with several .packages, and I can't seem to figure out what's the issue here. I'm just figuring this Studio thing out so I'm not very well educated on this. 

It gives my sim a very pixelated look, it's supposed to be contour and highlighting make-up. I'll try to take pictures and add them tomorrow. 
I tried to change the compositionmethod from 0 to 3, but that didn't help at all. The thumbnail got weird and it gave my Sim an overall clown-look, with lots of white and red blocks and a big fat ? on their forehead. 
Then I changed the sortlayer from 7500 to 2100, I read somewhere that 2100 is the best for blush. I don't know why I picked blush, just to try it out I guess. 
Didn't work either. The white and red blocks turned black. Also the thumbnail was still weird.

Can someone help me, please? I really want to learn how to fix these things because I have the same issue with more than one .packages file, but I just can't seem to figure it out. 

I don't have dropbox so I don't know how to upload the .packages file here?

Really hope you guys can help me!
