ArcGIS 10.2 Activation Problewm

Hello,

I'm in University and have ArcGIS Desktop 10.2 One-Year License version. I installed ArcGIS and tried to activate it with my authorization code but it does not work. My disc came with an authorization code in the box.

Currently when I go to ArcGIS Administrator I have it set to Standard (ArcEditor) Single Use. I always get a pop up saying the following message:

Error
7174:Only deployed entitlement line can be fulfilled. Incident# 8215-192698142

Any help is really appreciated. Thanks!
