Student License Expiration?

Hello everyone. I'm a student using Creo 2.0, or at least I was. Recently I tried to load Creo at home and received the following message:

--

License request failed for feature

Requesting CREOPMA_Student2...

C:\ProgramData\PTC\Licensing\BK390206EDSTUDENTUNICL_license.dat:(-10)Feature has expired.

There is more to the message but I think this should be sufficient. I looked up the FAQ section and it sounds like this usually occures when the network card is changed but my network card has not been changed. Any suggestions as to how I should procede?

Thanks,

Ryan
