License error 9 during fatigue analysis

Hi, while running a uniaxial stress-life fatigue analysis during fatigue analysis with OptiStruct intermediate examination I get the license error 9.

Also, checking the license setting I have noticed the same error 9 despise of the license is activated.

However, I have already tried all the tips to fix this issue (listed below), I am still getting the error 9 and I cannot complete the certification.

- check the Ethernet ID: 

- license file name and location:

- add the variables

-requested new license

Can you help me, please? what should I do?

thanks
