New CodeMeter dongle had its licence updated for ArchiCad 19. After that there's been an unexplained problem I can't solve.
Can there be a problem in ADSL settings? It is using bridged connection to get through or maybe a NAT problem? Or maybe dongle has a problem with licence key..
You may have it sorted by now, but just in case... Graphisoft here in New Zealand had an issue with the telecommunication network. Once we reset our Internet Protocol properties we were all good.
Yours might be different, but ours were:
Prefered DNS server 8.8.8.8
Alternate DNS server 8.8.4.4
