His cable has a BM chipset, not an RL. That chiset doesn't support licensing. Makes me wonder if the cable is authentic (not a dig at you OP).
Oh well. I'd love to use the same cable for everything. Sigh. It's the real deal, purchased directly from Ross-Tech in 10/03/06 when I bought my A3. I pulled up the receipt in my Gmail:
This email confirms that you have paid Ross-Tech $439.50 USD using PayPal.
