Regarding the link to lesson U-03 in "Common Topics" on the SlicerIGT tutorial page

On the SlicerIGT tutorial page, the link for lesson U-03 in the “Common Topics” section is broken and I cannot open it. I wanted to connect the NDI Aurora Sensor to 3D Slicer using the Plus Toolkit and import the positional information measured by Aurora in 3D Slicer, but I do not know how to connect it and am having trouble. Could anyone please fix this as soon as possible?
