Student licensing error

Hi,
I got license error code: 9
 
I have done everything from this topic:
https://community.altair.com/community?id=community_question&sys_id=55d6ccba1b2bd0908017dc61ec4bcbd5

I have checked the ethernet physical address, and it's correct. Also i checked the license file altair_lic.dat ethernet address and it is the same my computer use. 
I blurred last 4 digits. 

I have downloaded the licence file from email and placed it to security folder.

I have checked license file name and it is not  altair_lic.dat.dat.
I have tried to contact altairuniversity@altair.com, and they send me 4 times same instructions. 

What else is there to do?
