Moving wordpress fail. Help?

Hello,

I am afraid I may have thrown away hours of work by amateur mistake and I’m hoping someone can tell me otherwise. Please help.

My site is oneoftheserecords.com/Site

I had been building the site in the “/Site” directory and renamed the directory to “index” in Filezilla, on the server. I renamed it “/Site” but now cannot access any part of the site whatsoever. I downloaded the directory and checked the main css file, which has my most recent edits on it, but cannot gain access even to the log in page to access my dashboard. Can anyone help?
