I purchased the upgrade for the 767-300ER PW from the MSFS 2024 Marketplace, but now all my liveries have disappeared.

Initially, I left the folders as they were in MSFS 2020 and updated the layout.json file. That didn't work. Then I downloaded the 767-300ER and noticed that the folder structure had been adapted to MSFS 24. So I changed the folders to the 24 format and updated the layout.json again. Again, no luck, since a livery.cfg file is missing. So I created one, but without the "required tags," that won't work either. I hope someone can help me and that I haven't just wasted my money.

Thanks for your help .

where can I find the sdk

I have custom liveries that aren't available in the Marketplace because I designed them myself. I'd like to continue using these. I tried following the SDK instructions, but since all the config files and other important files are encrypted, I can't edit or change anything because the SDK doesn't recognize them.

Perhaps you could provide me with the required tags for the livery.cfg file (perhaps via PM)? I paid for the product and want to use it with my own liveries, not with liveries forced upon me through a livery pack, and I don't want to spend any more money.
