I believe that is the old "Timberline" tray. You might just call the shop and ask. I hear they turn work around very quickly.
I messaged them but the response wasn't too encouraging, being in England it looks like my options are fix it myself or find someone local to have a try. Not sure I want to pay someone to troubleshoot when they could spend days on it and still not fix it so I guess it's down to me.
