I'm not a "PCM master", but you will need the dealer, or somebody with the correct software & tools to program the new PCM first, putting your vin in it, etc. With Lt1edit's licensing setup, you wont be able to use Lt1edit on the new PCM either. The cable is locked to the security seed #, which is unique to each PCM. You will need to get with them, and probably send your cable back for an update. If you could get somebody to pull the chips in your old one, and flash them on the bench, you would be back in business. If you keep both PCMs, you will need a second license from the Lt1edit people for the new box.

Good luck, Ed
