There are a bunch of things that can be annoying, for which there are either workarounds or solutions, and you will nearly always get much faster response time from the forum than from Cakewalk staff - though they also frequent the forum.
It's just that there are more of us than them, so the chances that one or more of us can help you is greater.
The on-line error submission process DOES work - things do get internally worked and prioritized and reacted to, and while it may seem as though things are not responsive, it may just be a time it takes to get to it kind of thing.
Again, the forum has seen most of the kinds of things that can trip you up with all of the versions of Sonar, so I suggest you post the issues and let us help you.
There is a GIANT bunch of accumulated wisdom here in this forum, and folks will bend over backward to assist you, if possible.
Most errors are not crashes, and most can be fixed or gotten past, so please post each of your issues as a separate thread, so things don't get mixed up, and let's get your current version fixed up.
Please note that if there are system things affecting your current installation, then you may well continue to have those issues in X3, even though they may be caused by something outside of Sonar.
I look forward to helping you - let's get started.
