I'm sorry, that is not the same error message. The one I get doesn't mention dumper, the one you pointed me to does not mention (unknown package ID). I looked at the VSS writer and it's for SQL Server 2008, which was installed well after I was getting that message, so I don't think it has anything to do with it.

The troubling thing is that it doesn't say what version of SQL Server in the message. It's difficult to know what to do when you have no idea what version is causing a problem. Crappy error message, if you ask me.
