Kanep. I'm using the Tricaster mini 4K and having the same problem using the A Score Creator not seeing a mirror host. I have the latest updates loaded. Can you advise?Make sure you update Animation Score Creator using the TC1 software update, an update was required so it could 'see' the newest TriCaster software versions.
You might of though it was selected during the install previously, but what can happen is the TriCaster updates first, it might initiate a shutdown and then ASC never got a chance to install. Run the installer and only check ASC to install.
No license purchase is needed for the copy running on your TriCaster.
