Well, I've checked to see if it was an issue with your characters specifically, which it doesn't seem to be the case. (I felt this was unlikely to begin with, but doesn't hurt to check, right?) I also took a look to see if perhaps there was another party trying to illegitimately log in to your account. That also does not appear to be the case.
This is very likely a technical support issue, and I have a sneaking suspicion that they may have just misinterpreted your title/thread contents, as they can be quite busy over there and might have missed some of the information you provided. I wish I could provide additional assistance, but I'm afraid my knowledge doesn't quite extend into that realm. Scratch the drivers issue, it definitely seems connection related after reading through a second time. The university issue is pretty likely, if your campus has specific ports blocked off or restricted.
Aside from that, I would recommend contacting Technical Support, possibly via other means than the forums.
