Problem with License

Hello,

today I installed the studentversion of Creo 3.0 on my Laptop.
At first I had skipped the licenseprocess but the insataltion was successfull.

Afterwards I made the licenseidentification as it was explained in the manual.
It had stated that the identification was successfull, but I still cannnot open Creo Parametic as it says that I have no license.

Am I doing something wrong or does it take some time to acctivate my license?

Sorry for my bad english

Greetings
