I'm not experienced with licensing issues but I did find this TechNote containing a fix for one of the things that can cause the error you mentioned. (there may be many different causes for that error... In case the TechNote doesn't help, and if you don't get ideas from other people, you may want to open a service request with Mentor support)
Ok thanks ,
It was a too older mgcld deamon version .
Have a good day .
