I could understand it if Line 6 stopped developing drivers for the interface, and the latest windows or Mac. That happens with almost every interface at some point. Can you still use the interface with the latest operating software and another product like Amplitube, but just can't authorise it to work with Pod Farm? What if you were using an older operating software? If you can't authorise on any operating software, that would be quite unusual. That would mean that my Pod farm platinum license which is tied to the interface, would never work again. Can't think of any other company's that would do that and it would seem unfair to say the least.
