Missing page templates

Hi, I upgraded my theme to the latest version yesterday and I've just found out that I can't change my newspage anymore. Yesterday it was a blogroll, but now it's just a static page. I'm also missing the page template segment when creating new pages. However all my blog messages are still hanging in the backoffice. Did you take the blogroll out? If not, how can I get it back?
