Hey Mike I had similar problems with the Spider 2 on my mediator and my RapidRoad. I resolved it all by just starting over with a clean install. Never figured out why though.
If your willing to send me the card I can test it out on my machines as well for you and see how it responds. I've got one of every big box now for just these types of situations. I'll be gone and out of touch for a week until June 8th, but would have family at my house to receive if your comfortable with it.
