(Archived) Syncing on multiple devices except one

[jfouts 0]

Evernote syncs on all of my devices except the Mac Air. Old files load after I log in but I get a message saying it can't reach the Evernote server.

I've tried logging out, re-installing, etc but it's always the same thing with this one device, but it's working on all my other devices fine.

Help!
