Likely problem 1.
The patches stored at Institute of Noise are for pre-HD Workbench and will not work with HD, correct?
I just tried to upload a .whd file to IoN, the site will not allow the file type .whd.
I changed the type to .vwm and the page said the upload was successful, a user would then have to change the file type back to .whd before using it in Workbench.
Unfortunately when searching for the patch I just uploaded it does not show up and the most recent patch shown is from 2009
As I recall there was a notice on that page years ago or maybe I recall reading a message from Andy Z somewhere that said IoN was no longer accepting uploads,do not see the notice now - I am giving up on it but maybe someone else here will have more success uploading new tones to that page.
FWIW - User Created Variax Workbench Files are traded here:
