Yeah I agree with @krabbencutter about the “NIC”. The Waves licensing facility utilises it as a unique ID for your computer and the whole authorisation system is centred around it. If there is a problem with that, then you’ll have problems with your Waves problems.
I’m not “against” Hackintosh’s but they are notoriously problematic and generally hard to keep maintained and updated, which really gets in the way of using it for its intended purpose, making music. I usually advise against going down this path for this exact reason.
You may think you’re paying more for a Mac, but when you add together the cost of its parts its roughly worth the equivalent off the shelf PC. The other thing people seem to miss is what you get on top of a high quality build is the guarantee that it will be supported for a number of years, not just Apple, but all the third party application and plugin developers as well. Consider also how much you could be earning with the time saved by not spending countless hours messing around with your setup. This kind of assurance is worth the extra overhead alone. Unfortunately, none of this helps you now.
My advice to you would be to get your ethernet card working.
I don’t think this forum is a good platform for that, though. Try a Hackingtosh forum, get your card working and we’ll try to help you sort out issues from there.
