The Custom User skin I make simply isn't working

Recently I wanted to make a custom skin for my tank, however what ever I do, the skins I make just doesn’t appear onto the tank in game, all I did at first was something simple, like a scribble or just changing the color, no matter what I do it just won’t appear in game, then I downloaded someone else’s user skin I found on war thunder live, nothing much just a random one and tried to replace his turret skin with my own and when I returned, the turret just had default camo, whilst the gun and body had the skin that I downloaded from someone else because I didn’t change those, I deleted my turret camo and replaced it with the original turret camo the “someone else” made and what do you know, his camo works fine but mine refuses to work. Then I just deleted the entire thing and decided to make another one, I went into the hanger, went to customize and clicked on the little wand thing that allows you to make a camo template of my chosen tank, but for some reason, when I opened the file, the camo on the turret, hull and gun all had the word “sample” on it, I tried it again, and again and again, its always the same, it all has the word “samples” covering the entire thing.

Please help, I don’t know what to do and how to do this.
