Creo 3 - Licence request failure

I have installed Creo 3 - this time I have got it to open up the latest version but I am

receiving the licence request failure message.

I used the educational standalone and removed all previous licences on installation.

I would appreciate any advice to get this running.

Shortly after posting this message I was sent the licence .dat file which I dragged and dropped into the licensing box and removed all other entries.

The same fault is happening. Is this a license for Creo 3 because in the email it refers to Creo 2.

I am not having much luck here.
