Today I downloaded the skins I had submitted manually, either from the webpage posting if the skin was a new addition, or from the AH skins page if it was an update to an existing skin.
1) My 3 B-17Gs are listed in the selection list in Red text, as are all other B-17G skins except for 3 of them.
2) The two new P-51D skins I submitted do not show up at all the in the list (p51d_39.res, P51d_40.res).
3) The 3 P-38L skins I submitted, all updates to existing skins, show up in red on the skins dropdown but aren't available, even though I downloaded them manually and put them in my skins folder.
As far as troubleshooting, this is what I've done:
1) Restarted the game,
2) Rebooted my PC and started the game, and
3) Renamed the skins.res file and restarted the game. I get a new .res file but the problems still remain.
<shrug> Anything else I can try?
