Transferred to squarespace domain and hosting but need my old website info

Hi there,

I have spent hours trying to figure this out and finally cracked. I need your help. I transferred one of my domains from 123 reg to Squarespace. I was using www.ads-software.com as the hosting and now that the domain has transferred over I can’t login to www.ads-software.com anymore – it says account doesn’t exist. I assume thats because Squarespace now hosts it too? So my problem is I need the information and content on the pages I created in www.ads-software.com. How do I get that back? Squarespace and domain people said that www.ads-software.com will still have it and i can get it back, is that true? It’s a lot of info and would take me weeks to rewrite so really need it.

The website is https://www.corehealthchiropractic.co.uk

Thanks in advance for any and all help!
