C125 won't accept updates

[Dsqr]

I have tried to update my Raymarine instruments on three occasions. I have the following instruments installed:
C125
RD418HD
I70
Wind Instrument
ST6000+
Ray70 and remote

On the first try, I was able to update the radar, I70, and Ray70, but the update to the V14 did not occur. On the second occasion, I attempted to upload V17, without success. Just recently, I tried to upload V19, again without success. I have tried the updates both in power on mode as well as going through the set-up menu.

After reading your instructions to another user, I tried loading the Lighthouse chart in both slots. I was able to see the charts in both tries. I have tried to copy images of the files that I used but have been unable to do so. All three files show the same zip format.

The boat is in Racine, WI

Please advise.
