Camara texture issues

[Nightingale]

For some strange reason, the Camara textures got distorted when I updated from 4.86, and it's finally started to bug me. Researching the bug report thread implied that this is due to an old MAT file. However, I've re-installed and cleared out the FL and Disco folders as well as the registry two times now, and it seems like at least my installation cannot get the correct texture to work. Is there any way to get the MAT files outside of the main installer, like a separate download? I can't see any other ships with this issue, either.
