Just a dumb question, but are you putting it back in the right direction? I got a champion Redeemer for Christmas. The switch section is essentially the same. I was able to slide the card out and then put it back in.
Although on the back of my card, instead of two long bars, mine has what looks like two half O-rings in the same place. I opened the card and slid it up as far as it would go, then pressed it down over the power button turning it on, then was able to slide the card the rest of the way out. Is this how you did yours?
