Don't doubt it my friend
EE v2 after beta around r21/2 requires internet connection (check the store).
If you can run EE on your phone I would be impressed!
It works well at home because you most likely haven't set up a strict firewall like uni.
Your EE v2 is trying to verify your computer ID with the EE server to confirm your copy is valid, it's failing most likely because you are behind a firewall.
I suggested using your phone's 3g data, via BT/USB or create a hotspot and connect your laptop to it, then restart EE and it will connect, verify and you can use it
or go to mc donalds or star bucks etc for free wifi and connect there
Trust me, I know what you are going through, that's why v1 is still the popular choice!
