Uploading liveries seems to be a problem in all worlds. Best I can describe it, the image converter is broken and no longer converting improper image files to AE standards. Due to the improper image file, the game cancels the operation and shows the the error above. Anybody know why?
Workaround: Open up a new image exactly 800x300 pixels, then paste your livery in. Export it to a new file in .jpg, ensuring that the file size is not above 2MB. Upload to AE.
