WPMU Plugins fail to install on GoDaddy

A site/plugins need to be updated. I said I could help; wanted to upload snapshot pro. Tried to install the zip, and that didn't work. Then I tried to install the dashboard first, and that didn't work. http://screencast.com/t/Lnm4doILLPV My guess is permissions, but I'm not too familiar with GoDaddy's proprietary file system so I thought I would ask.
