I'm very glad you got it working!
I'm very sad it failed again.
When pushing the card into the bottom enclosure, we almost always 'torque' the front panel a bit.? This could cause the connectors to seat differently, or a cold solder joint to open up.? So it may be worth a few tries of repositioning the front panel onto its connectors (if you haven't done that already) to see if the problem will go away.

And if you are in the USA and send it to Jeff W1NC, you will get it back and fully operational much faster and cheaper than ordering a pre-built kit.
