WP Avalon messed up my home page

Hi, My WP Avalon wasn’t activated. I tried to activate it from my account But I couldn’t activate it because it says expired!! I couldn’t see any renew option on usability my account section. I use another account’s key for the theme when I activated it. It messed up my index page. I had already taken backup when I restored the site from backup I still see the promotion on my hero image.

Actually I had problem with my carousel so I wanted to update the theme from 1.0.6 to 1.1.0.

Please let know how can I fix it?

Thanks!
