Squarespace hero to fix my theme

I have been using Squarespace for 1 year and have been pleased with my website. I bought the 'Tuscany' theme from Squaremuse (they've now closed) and it's been working fine. Apparently it has to sit on 7.1 Version - which it is as far as I know.
My website is all there, just not looking as pretty....the theme isn't working and I haven't changed anything so I'm clueless. The only thing I can think of is that when my renewal for Squarespace came up the card had expired so they'd taken something off?

I have the Tuscany Design Kit PDF attached so you can see what it should be looking like.
I'd also like to add the hero has a contributor to my Squarespace rather than sharing my login details as someone else on Peopleperhour has asked me to do which makes me uncomfortable.

I believe it's a super quick fix for someone in the know!
