SAM open source test

In the windows SAM build instruction (github.com/NREL/SAM/wiki/Windows-Build-Instructions), step 6 suggest to "Start a new project" on SAM's welcome page. However, after I click the bottom, a window comes out saying "Updating solar resource library..." and after a few minutes, the program stops.
Does anyone know how to solve this problem? Thanks!

Thanks Paul!

Hi Paul, thanks for the introduction. After I click "Start a new project" and choose a technology, the window of "Updating solar resource library..." pops up. And a few minutes later, I am able to get into the UI page but the entire UI becomes not responsive, and a window of "SAM.exe has stopped working" also pops up. I attached the screenshot on Github.
One more question. What I really want to do is to debug to view the code for the project. I would like to creat a project, input the variables and debug in Visual Studio to see how the model works. Could you tell me how to do it since I didn't see it in the instruction.
