Portfolio gone after updating

Hello,

I updated some things in Wordpress and somehow the portfolio of the Perth theme disappeared. I can’t find it back in the CMS menu… When i go to installed plugins it says Perth Portfolio is activated but its nowhere.

On my website you see the thumbnails of the portfolio but the pages behind there are all gone…

How can i get it back?

Found it. Its fixed. I imported the perth-settings.xml again and i was able to choose the projects again!
