Windows， can't load shaders！

Hi，@lettier ， after builing the project ，i ran the demo, i could hear the water and wheel sounds, but i could't load the shaders as above images show , don't know why... i just try both absolute and relative Paths ，still could’t load...

Do you or anybody ever meet similar problems ,or successfuly ran the demo on Windows ？ I used the latest Panda SDK building the Demo.

Really good demos，but there are indeed some issues when building it on Windows 。。。
