I bought a preowned EyeTV 250 plus that came complete with EyeTV 3 software and the activation key. I have El Capitan on my computer so I was unable to run the software that came with the device so I downloaded the newest versions from the Geniatech website and when I launch the program and run through the setup assistant I reach the section where I need to enter my activation key and it doesn't unlock the 'Next' key. What are my options here? I specifically was looking to get an Eyetv 250 plus WITH an activation key card to that I didn't need to shell out more money for the software. I've tried contacting Geniatech support via their page and have not heard anything back. I'd really appreciate any help/experience anyone has with this issue. Thanks!
