my friend used ez drummer to record the midi drum track on REAPER

but when i open it to my laptop (fresh installation of REAPER and EZDRUMMER)
this comes up

what does this mean? >.<

So I decided that I want to record all my drums using an electric kit. I also want to build my own out of Remo practice pads and piezo transducers connected to 1/4 female jacks.

Hi All,
I did a search for the subject I'm about to ask but no go. So here is my question: I plan on buying a electronic drum set that has MIDI outs and I would like to record the drums to MIDI so that later I can run the MIDI file with Drum kit from hell superior. Is there any program that will record your playing and save it as a MIDI file? Thanks
