License problem/ missing Target-ID

Hi,

I have a big problem with the licenses. I have downloaded the student version of Catia and the student version of Icem surf and every time i want to import a licens in one of the license managers, the other one is thrown out. So i can only use one programm at a time and when i want to use the other programm i have to switch the licens in the license manager.

We have discussed this problem in school and we thought it´s because i only got one target-ID and my class mates got two.

I really hope You can help me.
