In Need Help With The Instruments

Hello, im very new to Renoise and i have a kind of serious problem. I just downloaded Renoise a couple of days ago, and i have checked the tutorials for adding instruments. But the problem is, when i double click on the drumkit that is downloadable, a text in the bottom left corner says “unknown song filetype!” and nothing happens. Can some one here be so kind telling me what i am doing wrong and how to make some basic drumprogramming? :(

make sure instrument is the selected radio button
