HDClone 9 Pro update -- how??

Have used the app's notification service prompt to 'email' myself a link to the v9.1.5 update (i'm on 9.0.12b) -- nothing arrives and no email stuck in spam/quarantine.
Then i tried the workplace license button to launch the Update/Upgrade configurator, added my license key to hopefully get the link to d/l -- again it says there are no updates??
How are we supposed to update the product now? This worked fine on v4,5 and 6 if i recall.
As a side note, when i create a boot-able USB stick with more recent HD Clone versions, and have it fully registered/activated on my system -- stupid USB app still need to be activated each time!! WHY?
