Problems creating the A359 personal livery for MSFS 2020

[Freccia]

Hi, I downloaded the paintkit (Version 1.0.4) and created my livery, following the instructions in the included PDF file. However, they are quite lacking for non-professionals like me.

The paintkit contains 8 psd files, which I modified to create my livery. I ended up with 11 files (the A359_Master.psd file was split into 4 parts, as per the instructions).

However, once I converted the 10 files to DDS format (the "Registration A350Paintkit.psd" file was saved as a PNG file, "Registration_ALBD.png"), and uploaded the folder to the community, the airplane is completely white and the wings are pink, as if a reference to some file was missing.

For the sake of completeness, I'll let you know that I converted the 10 files from png to dds using https://www.photopea.com/

I'm sure I'm doing something wrong, but I'd like to understand what steps I missed.

P.S.: The "A350_Wing_Registration_ALBD.psd" file is confusing me; I don't know how to edit it.

Thanks to anyone who can help.
