Six year old post, with no replies, ironically this is the exact problem that sent me searching through this forum today. I recently swicthed from Sreets & Trips 2006 to Mappoint 2009, and even though I have uninstalled S&T the 3rd party program that is linked to Mappoint gives me the same registry error. I've tried uninstalling and reinstalling in every configuartion with no luck.
