I bought this accessory and it worked really well the first 3 times, but now my FS5 is giving me a message the it is not supported.

Any ideas what is going on?

just a shot in the dark, maybe because its empty? same message with the UWP in place?

It's the same message with a receiver in place. I called Sony and sent it in for a warranty exchange. The tech guy I talked to said there was probably something wrong with a connector pin. Which makes me pretty nervous considering I've only used it about a half dozen times and never in conditions that would have been pushing the equipment.

thanks for the update, I am actually a little scared to be taking the handle on and off all the time... those connections just do not look all that robust (LCD connector either come to think of it)
