Yes the Hijack crack still works with the latest Steam Update. But this is how I did it. Firstly I moved Hijacks cracks (the 3 files, I am still using Hijacks first crack) to a different folder, and started the game in online mode to get the update. Then after updating i shifted Hijacks crack back to where it should be. Then disabled my Internet connection and started the game in the Offline mode. Everything works fine still without the CD in the drive. And I only updated today!
