Materials Studio 8.0 License Pack

Hi 

I am installing Materials Studio 8.0 SP1 and having trouble with licence pack namely i got an error that is not accesible via the netowrk (screen captures attached). I am using Windows 10 and ESET security for managing firewall. Interestingly the same problem occurs with MS 2017 R2 but not the MS 7.0. Any suggestions? Firewall?

Regards
