Good to hear you have PC experience. Like any advanced, full featured software Sonar can seem confusing until you get familiar with it, particularly when issues happen at the outset as you are trying to configure your system. Hang in there - It is well worth the effort!
I am guessing you have plugged your keyboard/midi interface in, and it as shown up here
Edit > Preferences > MIDI - Devices Make sure your keyboard/interface is the ONLY OUTPUT SELECTED for the time being. Click 'moved checked devices to top', then 'apply>OK' to close the window
If you still are not getting midi signal, check the following:
When you load your midi file, in track view each midi track has a number, name, etc down the left side of the screen. If you hold hour mouse on the right hand border of this area the cursor will cheng to a resize tool. Left click and slide the border to the right, exposing more controls for each track: Volume, pan, gain etc. On a midi track, the last of these are 5 dropdown menus: midi input, midi output, midi channel, bank change and program change. Make sure the second dropdown (O) is set to your interface/keyboard for each track.
