See my screenshot in attach.
I'm connected with a SQL Server 2008 Express R2 with service pack 1 plus Advenced Services.
I double click with left button mouse on - SQL Server Logs - Current -20/07/2012 15:06.00 to open the details.
After this I select voice - Server Objects - Server Triggers and I obtain the error that you can see.
Best regards.
