Creation of Vsi randomly works


I was eager to use this tool as I needed to provide my team some snippets I created on my machine. When I added to snippets, which are spread in different subfolders of the standard ..\Visual Studio 2010\Code Snippets user folder, I pressed the build button, provided a name for the vsi file. Strangly enough I did not get the confirmation message that the file was succesfully build as the example video showed.
I removed all but 1 snippet and build again. This time it worked.
I add more content again, and it fails again.
I'm not sure if the content of the snippets can cause failure ?
Is there a location I can review log files ?
I can provide you the snippet files for you to test if they are the cause of some evil.
kind regards,
