Damn... Sounds like the SCT device got corrupted if it won't let you change tunes all of a sudden and doesn't recognize the vehicle.
Worst case scenario borrow an sct that isn't vin locked and grab a stock tune from another 5.0 or load your lund cammed tune since that one works.
Sct should replace yours since it sounds like that's the issue and not the tune itself, I'd contact both vendors though. If it IS the tune (doubt it) they can send you a new one.
Makes me want to stay stock to be honest...
