Murasame to the rescue!!

Well, almost. Actually, I've got rather bad news fo' you people: University and "Work" networks usually have firewalls up to prevent people from using P2P (that's apps like LW in case you didn't know).
If you want to verify if that's the case for you guys too (it may not be) either ask around in campus or go directly to your IT department (if you think it's cool with them if you asked wether they block P2P or not).

If you want to ask your IT dep directly, you can try asking them if they block port 6346 (the one LW is using). If they are, you can try asking them if they got a port that they don't block.
If, and that's a big "if" if ya ask me, they do give you an alternate port, go back to your comp, launch LW, open the Options window (that's the Prefs for Macs) and go to Advanced. There, input the port that you know isn't blocked and click Apply.
See if you can connect.

In the (more probable) case that the IT dep will basically tell you that if you dare use P2P on their net you're done for, either start saving money to pay for your own connection (and, as a probable consequence, your own flat too), or just forget all about P2P and spend the money on CDs and stuff...
