Hi everyone,
this is a known issue when using other image software than Photoshop to open these templates
. Sadly my templates seem not to behave very nicely with GIMP or other. You will need a Photoshop (CS version is mandatory due to the folder/group structure issues) to take full advantage of all the PS effects. I know this is a sad dilemma as Photoshop is wicked expensive these days
Flybob, you are not directly telling what image software you are currently using, but the evidence in your images above strongly indicate it's not PS. So this is why the rivets aren't showing correctly. I can see also that the fabric-textures (ailerons etc.) are not functioning as they should. I can only think of that your current software does not recognize PS layer styles-effects and blending modes which I use heavily with my templates.
What you could try is to buy the PS elements (Cheaper but with less features) to get over this problem and fully enjoy the rich world of skinning. You may have to further update the elements to get it fully compatible with the templates, but it'll still be way cheaper than purchasing the full product.
