Adding a ris-file

[Hannakra]

Hey (:
I'm trying to start a new project, but I have problems adding my dataset. When I try to add my ris file, all it says is "Adding...", but nothing actually happens or at least the adding process doesn't succeed.
Do you have any ideas what I can do?

Best!

What is the message in the command line interface??
