Some questions I have to answer before I can troubleshoot this is:
Why does HSSE not show up in VEPro as a VST plug in, but only as an AU plug in?
Why not as a Multi, only Stereo?
Why is the file downloaded from HSSE Free Download (link provided by email from Steinberg) named exactly the same as the file for “Update- patch” from the upper link on this, the same page that provided email application for the link to the HSSE Free Download?
