Cit and Oct, I just wiped out my skins at home (both the res files and the cache folders for the skins), downloaded and installed the skin pack (made from the release we did this week), and I looked the skin you referenced.
Now I am at home, so I do not have access to the source files, but the skin I loaded has a shark's mouth, the number 38 on the right side of the fuselage, and is brown and green. Does that sound right?
If you want to make really sure you have the right skins downloaded. Do this:
Navigate to the Aces High installation folder.
Then got to the 'skins' folder.
Remove all the p40e resource files (p40e1.res, p40e2.res...). Also remove the "skins.res" file.
Then go to the 'cache' folder and remove all the p40e folders.
You will have to wait for the download online, but then all should be right with the world.
All these gyrations will be removed in the near future.
This all happened due to a duplicate skin in the p40e list being removed, but your skin is still there, just in another slot.
