HI Daniel,
As you mentioned, you are using "V:\yadayada" as destination. Mapped drive is not recommended by BusinessObjects to use as destination. Because they often get disconnected at server restart/reboot/ or any network hiccups.
It is always recommended to use UNC as path for destination i.e. \\Servernanme\ShareName\.
Also check whether account running SIA has appropriate Read + Write privilege over the file Destination.
