Scrivener and Papers Citation Software

Hi there,

I have just downloaded trial versions of both Scrivener and Papers. In general options I have selected (go to the folder) and selected the papers .exe. In the F12 options it new says Papers on the left of the selected/reset buttons.

However, I can’t seem to insert a citation link. When I hit Ctrl + O it brings up a folders search option. When I hit Shift + Ctrl + A it makes a red box around the selected word, but I can’t seem to link a citation this way either.

Can someone give me some advise on this? I am wondering if it has something to do with having trial versions of the softwares.
