Many thanks for posting. I was a recent victim of SonicStage crashing on startup and after many attempts to get it going again, (reinstall, system restore, sweaty palpitations, etc) I came across this thread and tried the Safe Mode fix and it worked for me too. I can relate to the joy you experienced last year!
Despite the obsolete issue I've been carrying on with MD/SS regardless as it does everything I want from a portable/music management solution. However, this issue with SS was a bit of a wakeup call. It's made me nervous - will SS continue to work forever or is it wise to plan for the future without it?
