Well since Giga 3 has nuked my OS drive it looks like I need to either reinstall Windows, format and reinstall, or just start from scratch on a new drive. I know there are instances where you have to re-authorize the Kontakt products when making hardware changes, but I am unsure as to whether this would constitute a reauthorization. I have all my original codes and everything that were emailed to me. Does anyone know for sure if I can get away with adding a new OS hard drive without having to re-athorize the Kontakt products? If I do have to go through all that I may put it off a while longer. I'm not crippled, but the PC is just going haywire on me.
