Cubase 5.53 64bit, superior drummer won't record

I bought a new computer, added Win7 64bit, loaded my older Cubase 5.5.3 64bts, Loaded my SuperiorDrummer 2, SuperiorDrummer won’t record. When I load S.D. onto Cubase, it makes it’s own set of tracks. I get a volume signal, but no record. ToonTrack tech. help says that it has to do with routing, but they don’t know how to fix it. Does anyone have suggestions? Thanks! Kevin, kev10
