error when running fetch.sh

[alebba01]

I've been trying to setup the package, and I keep getting the error:

Resolving c.yosinski.com (c.yosinski.com)... failed: Name or service not known.
wget: unable to resolve host address ‘c.yosinski.com’

when the script gets to the line:

fetch_and_extract caffenet-yos_max_im.tar.gz http://c.yosinski.com/caffenet-yos_max_im.tar.gz unit_jpg_vis max_im/conv1/conv1_0000.jpg

If I try to run the toolbox after this, it will not show activations for the currently selected photo, nor will it show classification results (the top 5 under the image are all 0.00). Is there something I am missing in the setup?
