Attansic L1 driver for P5K family disables Waves Plugins on iLok. Just for your information. Waves plugins need a perfect working ethernet to work and for some reason the Attansic L1 driver project stuff won´t report good status to them. Reinstalling my trusty Realtek PCI ethernet card, they all worked again.

Probably ilok associates your plugins with your nic's mac. So if you no longer have the old one on the computer, ilok would think you are trying to run the plugins in a different computer and so, they are disabled.
