Download failed. Couldn't resolve host 'premium.wpmudev.org'

I'm not sure why I'm getting this error... I double checked my profile and list of sites, updates are still enabled... I'm just trying to update the dashboard plugin, since I realized it was out of date when I tried to install a new wpmudev theme and it said it was installed, but then it wasn't there to activate...
