Create Use Case diagramm

Hallo everyone,

About two years ago I successfully used Aris Express to create Use Case diagramms. Now I downloaded the newest version but I cannot find the former possibility to create Use Case diagramms. I'd like to create them as typical, with actors shaped like stickmen. 

I would appreciate if you can give me a short advice if it's still possible to create this type of diagramm.

Thanks a lot,

Martin
