too much license

At least for the AA license, it can be used even after graduation.

Free Software for Students
Whether your school department has chosen an Online (downloads-only) subscription or an Online+Media subscription, you are able to obtain free Microsoft software with a license that never expires—even after you graduate! All you have to do is:
Register the MSDNAA products you install with the provided product keys
Adhere to the license terms of the Student Use Agreement

But again, check with your school. And in any case, you still havent told us whether you are not able to actually activate/validate or you're just wondering about the possibilities. Doing a phone activation is no big deal in any case.

Try this method for telephone activation without having to speak to anyone.

Click Start and type slui.exe 4 in the Search Programs field.

Double-click slui.exe 4 under Programs to open the Windows activation wizard.

Select your region and telephone the number given to use the automated activation wizard then follow the instructions carefully.

Once you've activated you can then create an image of your system for backup as suggested earlier in the thread.
