I will post more as I get more details but here is a heads up. Today a big Windows 10 update (2004) came through. Now my Waves plugins have lost their license. I strongly suggest you move any licenses to the cloud or a USB stick before updating Windows at the moment. Edit  - I suspect this is due to a previously disabled network port being re-enabled in the update. My C-drive which contains the licenses is shown as disconnected in Waves central.
