I've bought and activation key for my WF-3720 but I can't activate the chipless firmware.
I'm getting the error message:
CHANGE USB PORT. CHECK NETWORK CONNECTION, MAKE SURE THAT PROXY IS NOT USED AND DISABLE FIREWALL.TRY AGAIN LATER. 10060)
I've checked the internet connection and I can't reach the server.
I've also tried a other internet connection but the same error.
Is there someone who can help me with activating my WF-3720 chipless firmware?
Is the server online and reachable?
