[CA] [CA11] Software updates

[[email protected]]

I have never been able to get an email with the download link for software updates despite trying dozens of times over a couple of years. A Raymarine support person sent me a download link via Facebook messenger which has worked up until now. Today I downloaded a zip file which contained two .iso files;
raymarine_atom-3.8.97.upgrade.iso
ray_mfd_AtomCartographyRX5v1_22.upgrade.iso

I copied the first file to my sd2 card and tried the upgrade and it failed with a message stating a corrupt file. I tried the whole process again with the same result.

Are the two files above correct to upgrade my es98 to the latest software, 3.8.97?
If so where can I get a file that is not corrupt?
Why don't I get the download links emailed to me, (I've tried several email addresses).

Thanks
