Cannot synchronize music folder to library

I just cannot sync my music folder to Audirvana library.
I’ve tried auto ‘Rescan folder’ option on&off, and manual refresh button to add new files to the library.
None of the works.
And when I click that refresh button, it shows an error message which doesn’t make any sense to me
‘unhandled Exception: bla bla bla’

Can you send use your logs of Audirvana at this mail address (i sent you the path in PM) ? support@audirvana.com
