Go to the Catalyst menu
select option 'create support PDF profile'
this will create a PDF - which you can email

'Full scan' creates thumbnails of the content - and if you have corrupted content will indicate where this might be at the point it (unfortunately) crashes...

'Quick scan' (when you hold shift - or select the option from remote menu or webserver) - does not create thumbnails, and is quicker for lots of content - but may not indicate if there is any corrupted content.

Have you figured out what was happening both times when it crashed?
