I purchased an Activation Key for my Epson XP-241. I follow the procedure but na error appears:(COMMUNICATION FAILED. PLEASE, CHECK CONNECTION BETWEEN PRINTER AND PC.CHANGE USB PORT. CHECK NETWORK CONNECTION, MAKE SURE THAT PROXY IS NOT USED AND DISABLE FIREWALL. TRY AGAIN LATER. 10091). I deactivated all firewall. Do you know what's going on?
