Problem with  "ARM License Manager"

Hi all,

I have a problem with the license.

I have installed

-     Eclipse Platform

      Version: 3.7.0

      Build id: I20110613-1736

-     ARM DS-5

      Version: 5.17.1

      Build number: 5171010

But when I want to obtain a license and I press "Help> ARM License Manager" does not open any window.

Have you any idea on this problem?

I also tried to remove the DS-5, reboot pc and re-install all, but no change.

Regards

Alberto
