question about wavelab

[emeryrecordingstudios]

Hey there everyone! I was thinking about using Wavelab to master my stuff because I keep hearing how awesome it is. My problem is, that Wavelab is only for PC and all of my plugins and everything I purchased for Mac. For example I bought the Waves gold package, do I have to re-buy it or am I allowed to install it and use it on a pc?

Thanks,
Eric
