32 bit plug ins would crash Sonar Platinum.
I stopped using them.
I cannot live without Mr Tramp, a 32 bit only Wurly VST.
So I thought I'd give it a go and lo and behold I now have it in a dozen or so songs again and I have not had a crash in months. So for me it's the opposite. CbB is the most stable by far.
I even break one of my steadfast rules and leave my internet connected most times.
Your issue must be one of those weird ones that something somewhere needs changing. It is defiantly not the Software or this forum would be crazy. It's been kind of quiet here since last summer.
PS ,, good to see you back, I don't think I've seen you post for a long time.
