If you own a working copy of ArtCAM 8 on an old PC, stick with it. If you are a new user, do not buy a used CD from eBay—the license activation servers are dead. Instead, purchase VCarve Pro (best for 2.5D signs) or Aspire (best for true 3D relief).
Ultimately, ArtCAM 8 is a classic—a "vintage" tool that, much like a fine manual milling machine, does one thing exceptionally well. Respect its limitations, understand its legacy, and it will carve beautiful wood, foam, and wax for another decade. artcam 8
