Hi, a bit new, going through the online tutorials and documentations. I have three computers, two macs and a windows. I've installed clean Blender and CrowdRender softwares in each and none of the three computers are passing even the render locally test. Where, you just press render and expect the image to render locally. The window pulls up, but it just stays blank with no additional information. I'm also unable to get the three units to network together, but figured up river fixes might fix downriver network problems.
