I received the same error in a test environment where I was running SSMS 2008 on my local box but connected remotely to a SQL Server 2005 instance. I believe something changed in the .trc formatting from SQL Server 2005 to SQL Server 2008 R2, but I'm not clear yet on exactly what it was. If anyone has information on the details of those changes, I'm very curious.

And I agree with codebyo - great series!!
