Woo commerce Spirit theme does not compatible?

Hi guys. I just joined wpmudev. I heard that upfront builder is a great thing. I did my woo commerce shop with X theme. They are very good but it seems to me that your upfront builder beats their corner stone. Anyway, I installed Spirit theme. All pictures are blurry and woo commerce shop is ruined. I thought it is not going to be a problem to use shop with a new theme. Could you shed a light on it? I need wordpress because of woo commerce. Thank you Philipp
