Why is nothing loading under 'Online Store' after Basic Plan activation?

I have just activated the Basic Plan after the demo expired and there was a Theme in use with the demo. It no longer shows in the system and everything under ‘Online Store’, such as ‘Themes, Blog Posts, Pages’ etc will not load anything.

How can I fix as I cannot get hold of any direct support from Shopify!!? (All leads to articles and nothing else).
