It's not needed to be updated when it's already installed on printer.
But we update it when there is new firmware from Epson which blocks ours.

Download the latest firmware from our website and try it.
 

You are right. I tried the latest firmware from your site.

It was installed and activated successfully. 
Thanks for help!

WIth some latest updates Epson block downgrade for printers.

Do you use latest firmware from our site?

I used Firmware from when I downloaded it last time. I didn't download new one because thought your firmware doesn't need to update.
