Hi there!
I was using HyperMesh perfectly the day before and I have requested for an academic license (for my individual research project) from Altair, but unfortunately I suddenly faced this message today.
I have used 6200 as the port and JessicaLee is the host name for this machine as shown.

Error message:

I've put the license file in the security>bin folder:

Do let me know! I need to get back to using the software as soon as possible as I have a submission for my analysis coming up pretty soon!
