Gary, if any of your problems are currently listed in the Problem Reports forum, add to the threads that you have the same problem and add extra info if you can. Every bit of info helps the QA guys.
If the problems aren't there, create a new thread (one problem per thread) describing as accurately as you can how to reproduce it. We'll see if it can be fixed due to either user or system setup error, if not it can be logged as a bug and Cakewalk will fix it.
If you just roll back and don't report it then the bugs will never get fixed.
