Hi Marco -
Sounds like a texture corruption.
I have no control over the texture that is on the download link, it's the software on the page that created it - the one with the download link. It may have been corrupted on the way over to you (I suggest this because there have been over 400 visitors to this one, and you're the first person to report a problem with it, which suggests it is a download problem).
I would suggest that you try to download it again and see whether the texture arrives intact, and perhaps let me know whether that was the problem.
If the texture comes across badly again, you can always use the one I've attached here, which is just my download from that same link. If that texture works, it still points to a download corruption.
The quality and format of the texture you get is something controlled by Charly's clever use of graphics software through a web interface, and in all the ones I've installed, it has worked very well. But while I manipulate bits of the texture (coloring in the livery templates, placing elements, and sizing them), that's all the control I have over what comes out!
If there is a corruption in the source image, that would be for Charly to fix since it would be the functionality of the repaint process that was creating a problem.
Also, be aware that I also manipulate the DDS image when I download it, because I use FS9 and the web page won't let me specify that I want the texture as BMP. My conversions of all of these textures to BMP have gone fine, including this one. As I say, I reckon it is a download corruption.
