Trouble Loading from Streaming Assets Upon Build (Windows)

Hello,

I have been trying to get a Windows build of the current state of my game to run correctly, but the data files from Steaming Assets do not seem to be loading (and are probably generating an error that prevents other initialization methods from running).

Of course, there has been no such problem when playing the game from within the Unity Editor.
This is how I am attempting to access the folders in Streaming Assets:

Code (CSharp):

1.  
2.          string sa = Application.streamingAssetsPath;
3.          string nationsPath = sa + "/Scenarios/" + scenario + "/Nations";
4.          string[] nationFiles = Directory.GetFiles(nationsPath, "*.json");
5.  

In desperation, I even tried keeping the .json files in Assets and accessing them from there, but that did not help either.
Can anyone suggest to me what I am doing wrong here?

 

any error messages in the player.log?

Thank you mgear. Previously, I was trying to find some kind of log in the build files and, of course, found nothing.
So this is what I found:

In addition to this, there were numerous

Code (CSharp):

1. Material AddUI doesn't have _Stencil property

errors, which might also be causing trouble.

 

so it seems to load the json, but then fails with those errors after that, what are you doing with json there?

*looks like someone fixed similar issue with this,

My problem turned out to be precisely the same as in the links you gave.
Thanks so much mgear, I owe you one!
