I think the issue is with the Windows Fall 2018 updates. Just recently all my programs that use a license validation seemed to stopped working. I can’t get eLCC, iLok License Manager, or Waves Central to work anymore. I chatted with Microsoft today while they walked me through several fixes and none worked. It seems like the last solution will be to do a fresh install of Win 10 but I don’t think that’s going to work. There’s something in Win 10 that’s preventing these license validation programs to work. I sure hope someone can figure out a solution soon because it’s very frustrating to have things work one week, then go to use them again and they’re not working.
