Pro is activated but newly designed page reverts back (like in basic) when I leave the page

In Wordpress, before I bought yellow pencil pro I could design a new page but it couldn’t be used. After I bought pro and activated it, I still get the old page. The new page disappears. What do I need to do besides activate pro?

I have the same problem. All yellow pencil changes stored by not active on the real website !!

Who can help?
