Hi Bob, No. My BIAB & DAW may be "older" .....(but they have always been able to do what I needed of them)..... but my PC is almost brand new ....dual core, plenty of power & memory. I had tried "return to factory settings" without success. Eventually I decided to uninstall both BIAB & Real Drums. After being re-installed , I was able to 're-render' the Real Drums track ....imported the .wav into Sonar and everything seemed to line up. So far.....so good. Thanks for your interest Bob. Joe G.
