Just copy-paste as said before, you don't have to open or edit that file. It's like Steam stored the file at a "wrong" location, the game can't find it.

I opened my files now what do i do?

It's an old Workshop issue. The craft is stored here:
C:\Program Files (x86)\Steam\steamapps\workshop\content\220200\2185665618

you can copy that .craft file and paste it into your craft folder:
C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\saves\XX\Ships\SPH

I just tried updating the file to solve the problem, but the Workshop won't let me do so. Instead, it will be posted as a separate new craft, which I do not wish. Bad problem. Sorry for the inconvenience!

I downloaded the craft but it does not appear in the game. What do i do?

非常欣慰！

感谢作者，按照你的方法问题解决了！！！

在这里面搜索一下载具名称，多半是在里面的，需要手动拖到SPH文件夹去
C:\Program Files (x86)\Steam\steamapps\workshop\content\220200
这个不行的话还可以去 KerbalX 网站搜载具名称下载
这问题真的很怪，完全不知道是什么情况，我自己也几个订阅了找不到...

我也遇到了这个问题，订阅之后在游戏中找不到。

怪事情，这类错误码我感觉一般是Steam/网络的锅，我上传文件的时候偶尔会遇到，一般过一段时间会好（希望

游戏重装，mod重新订阅都试过了，怪事儿。

订阅后在游戏中机库里并不能打开，直接点跑道倒是能发射，但是显示未订阅，点订阅显示steam错误码：k_EResultFileNotFound。还有个17的中继卫星也是这样，怪事儿
