Firmware update problem – urgent

HI Just purchased and I have exactly the same issue and the same error code
Why do you not post the instructions you have emailed If you had I could have tested them rather than waiting for a reply to my email sent today marked urgent!l
You seem to be aware of this issue so at the moment I have a brand new machine which is now useless as a result of your large instruction ( a4 page in yellow at the top of the box) telling me upgrade immediately to the latest version of firmware! I didn’t get 1 minute of use before a problem!
Not good
