Finally bit the bullet and updated to v 7.3.3335 because I needed support for Kontakt7 (VST3-only.) That meant moving from the old verification dongles to iLok on my two servers, but that seemed to go just fine. Installed Vienna Assistant, did the iLoc transfer to my account, down loaded and installed the new 7.3.3335 and on the SERVERS, everything looks good. iLok shows everything is activated, my old settings came over into the new version's preferences, and all my VST3s load perfectly.
HOWEVER, my DAW machine no longer sees the two servers. I made sure Bonjour was running on everything and that none of the machines had an active firewall going. I made sure the servers were set to broadcast their addresses. The three machines can see each other fine on the network, but from within the DAW, no servers show up when I either load an existing project, or try to start a new project and connect to a VEP server. DAW is Cakewalk, which was working fine with these two servers on version 7.0 for two years. All machines are running Win10 Pro.
This is what I do for a living, and I'm now unable to work. Considering restoring the machines from a backup and continuing without VST3 support, but since the licenses are now sitting on iLok, I imagine that my old dongles won't be able to run the servers.
Any suggestions would be appreciated.
