I had this problem over a week ago. One of my radios' Barracuda module gave up its ghost, so I transplanted a spare, but I have been unable to remove the expired module from my account, receiving the 'something went wrong' message on each attempt.
Looks like an ongoing problem then. No doubt the Reciva people are working so hard to resolve the BBC problem that minor problems like this one are being left on the back burner....
