Robb, i feel your pain, Reaper acts like that for me. I use both PT and RB all the time to playback and record stuff, i have very few issues.

When a software crashes consistently like you describe, it is usually the setup. I assume that since Reaper works fine for so many others, the it is my setup, and my system that is in conflict. RB is just one piece of software, and must run on ten thousand different systems, so it is rarely the softwares fault.

If Sonar runs fine, or Reaper runs fine, or Cubase runs fine use it. But if you want to dig in and really find out why the good folks here will help. Also call support and spend a few minutes on the phone with them. I can't say Rb is my favorite DAW, but i have come to really enjoy it, and it is unique.

Best Wishes Rob .. er the other Rob (1 "B")
