Flow Navigation has moved to CG Flow

Flow Navigation is now a tool inside CG Flow — one Blender add-on for all Flow tools, with one panel, one account and one update button. This standalone add-on is no longer developed.

Moving from this add-on: https://cg-flow.com/docs/system/#moving
Remove this add-on, install CG Flow and create your CG Flow account. If it uses the same email as your Superhive purchase, your Pro licence is linked automatically. If the email is different, or Superhive never had it, enter the order number from your Superhive account under Link an order in your CG Flow account.
