Sharpen AI 4.1.0 on Mac M1 Pro wont work (Processing Error)

Hey guys,
I hope you can help me out here…

Bought the Photo AI, Denoise AI, Gigapixel AI and Sharpen AI last week.
Everything works except the SHARPEN AI.

according to my account on the topazlabs HP i downloaded the Sharpen AI 4.1.0 version.

I run it on a new MAC M1 Pro 2021 (only a few days old)

when I open Sharpen AI it’s still in TRIAL mode.
when I try to log into my account it doesn’t do anything. (the loading symbol appears with the text “Authenticating user” - but that goes on forever)

when I try to load up a picture (in trial mode) I get the message:
“Processing Error - Error loading model, please try again. If problem persists try switching to a different AI Processor in preferences”

…but even I switch from “auto” to “CPU” or “M1 pro” in preferences…it won’t work.

anybody can help me?
