Please select edges for blending fail, Filled surface

Hi

The last two days I have bin struggeling to get solidworks to make filled surfaces. Whatever i do it says: please select edges for blending. If i just sketch an elipse or a circle and want to make a surface it won't give me a preview or anything.

The filled surface simply seems to be kind of broken?

I am runnig the latest version of solidworks. Does anyone know what the problem can be? Something with the installation or so?

Thanks for a nice and helpfull forum!:)
