Updated Barista Theme

I updated the Barista theme and now my website is a total disaster. I hate it. It doesn’t look the same and the coding is all different. Before when I updated I could change the code in the navigation to get it back to the same colors but now it seems that not only has the navigation completely changed but also other components which makes it a totally different site. I am very unhappy with this and want the previous version of Barista back. If this can’t be fixed or a copy of the previous theme can’t be provided, then I will be using a different program to rebuild my website.
