Please first try loading the organ via 'Design tools | Load custom organ', so that Hauptwerk will re-compile the CODM ODF appropriately for the sample files that you have installed, and, on the 'Load Organ Design Options' screen that appears, tick all of the 'Reset' options and make sure that the 'Skip all organ definition validation for speed [caution]' option is *not* ticked. Does that solve it?

Am I right in understanding that you mean that you get an error unless you have the relevant rank disabled on the 'Rank Audio/Memory Options and Routing' screen?
If so, please create and send us a diagnostic file ( http://www.hauptwerk.com/forms/support/ ) so that I can see the exact error message that you're getting.
