Waves plugins "could not be opened"

Simon James

I'm running logic pro x and have some waves plugins that I was using with another computer and did a migration assistant over to the new computer. I have the licenses all transferred over. My plug in manager can see the plugins but it says that they could not be opened. I'm not sure when else I need to do. Do I need to download all the plugins again? Not sure what route to take.

Thx in advance,
