C11 download assistant trouble

licence purchased, download assistant updated: assistant asks to sign in>> which opens browser to sign in, which i do. message:

Authorize Steinberg Download Assistant
To authorize Steinberg Download Assistant, you must allow your browser to open Steinberg Download Assistant. Once authorization is completed, you can close this page and continue working with Steinberg Download Assistant.

that’s where it’s stuck. the download assistant only opens to the sign-in page, which leads to the same cycle of signing in etc.
