I bought a used tuner and I can't get it to connect it keeps saying unable to connect to interface. I am using the keyspan with it and downloaded the version 1.2.4 and the keyspan driver from gmv6pcm.com and still have no luck. Red light on PT is blinking as well as the green light on the keyspan. Please help I want to start using this and i can't figure it out. i will try anything. Thanks
