That is probably in regards to the new version of STOREMI version 2.0 and not the old version of STOREMI.
AMD's new STOREMI v.2.0 is not based on Enmotus anymore but the old version of AMD STOREMI is based on Enmotus software.
So Enmotus is saying that you must go through AMD Support for the new version and not Enmotus Support.
Let Enmotus Support know that you are still using the old AMD STOREMI version 1.0 and not the new version 2.0.
Like I mentioned before when AMD was phasing out STOREMI v1.0, Enmotus was offering free Enmotus Support for a limited time to any AMD User.
They will be the best option to help you remove and fix your version of STOREMI issues you are having.
EDIT: I realize I keep sending you back to Enmotus for Support. Is that the first version of STOREMI was created by Enmotus so they can better advise you on what went wrong and how to correct it.
But if you want you can try and open a online AMD SUPPORT Ticket from here: https://www.amd.com/en/support/contact-email-form
See if they can help unless they refer you to Enmotus.
