problem with page creation - will not show content

I am currently trying to create my homepage and I am having real problems.
As I installed beTheme I accidentally installed the BeTheme Demo Data "Carver"
Then I installed the default to undo it but when I try to create the first page (Add Section, Add Wrap etc.)
it will not show me the image I uploaded nor the column content I am trying to create.
I don't understand my mistake, please help me!!
