Hi @nikdocz, I am afraid we do not provide publicly older versions of the Tobii Core software or Game hub online, but if you PM me with your last version, I can try to get these for you to test.
To confirm, you state the you updated *both* Windows 10 and The Tobii software or both? It would be super helpful if you could provide additional detail for us.
Did you try to disable antivirus or firewall software to test functionality? How about a different USB Port? Please also provide us your system specifications. Thanks.
