I feel your pain! I learned how to use it on my own after a lot of throwing stuff

so hopefully I can help.
This applies to SD2.0
1. You have to load SD into your project (I am hoping you can do that) it should ask you to select your output settings. Start with these: select midi>all tracks stereo or mono (up to you)>midi output
2. Once you open SD then click "grooves" from the menu in SD (you should have Pop/Rock default in there)
each set of grooves are dependent on what expansion packs you have installed and the default is Pop/Rock. If you have more they will be listed*
3. Once you open grooves there are a few lists to choose from and once you choose each list it will open a final one on the right with (ex: closed hi hat, open hi hat groove clips etc) the list on the far right is what you drag to the midi track in clips pane view.
4. Arrange clips into some sort of order to make the drum grooves. Keep your snap to grid on to make it easier to arrange in time.
hit play on the track and you should hear the clip you dragged over. You have to drag each and every clip you want to make the entire drum track. (once you get good at this then you can use a keyboard to make your own grooves)
refer to Cakewalk set up manual to set up midi output.
Once your drum tracks are the way you like then you have to convert the midi track to an audio track by bouncing the track to a new track. (this will make a wav file and convert it to audio). I believe it is in edit menu at vert top ring menu drop down. Bounce to track is what you want and in that there are choices so select TRACKS for whatever number track contain the midi SD track clips. If you have the SD set to multi out it will make a separate track for each kit piece: kick, snare etc. I like it that way. (sorry not near my pc at the moment)
If I can help more just ask! I'll do my best to help. I have been there like I said and now use SD and EZ Drummer all the time. I love it.
