Hey , sorry I lost site of this thread. Yes all of the registered plugins you can use in X2 will be available in CbB. and yes it will open all of your X2 projects. CbB was built from Sonar Platinum so its' really just a couple of upgrades from X2 even though it is a completely different install. "Nothing" gets erased from X2. If anything comes up missing just make sure your scan paths for plugins are right. mark
