The organ ID 1340, is clearly assigned to CLR resources. Virtualpipes has been asked by us and by Milan Digital Audio to change their organ IDs, you may wish to contact them and request a new download.
Absent their cooperation, you can open the .Organ_Hauptwerk_xml file with a text editor. There will be an XML tag toward the beginning of the file that looks like this
<Identification_UniqueOrganID>1340</Identification_UniqueOrganID>
If you add "80" (or "8x" x=0-9) at the beginning of this, it moves it into the block of common numbers used by the CODM. The new changed tag would look like this
<Identification_UniqueOrganID>801340</Identification_UniqueOrganID>
Save the file, then this will allow you to load the instrument and not collide with our OrganID numbers.
