Lightroom won't let me add photos

[Gatita5FB4]

Hi!

I am trying to add photos to Lightroom CC and my ''Add Photos'' and ''File>Add Photos'' buttons are grayed out. So it seem impossible for me to add anything. I also tried to drop my photos directly in Lightroom app. And I've tried restarting and signing in and out but it still doesn't work. 

(I have the latest version Lightroom 4.0)

Any idea what could i do?

Thank you 🙂
