It wants some cheese Carol.
To be serious though I think I would get a new one.
We always have a spare just in case this happens because we have to wait for my son to come and undo ours because neither hubby and I can manage fiddling things now.
This reminded me of an incident the other night when hubby could not get his arrow to go where he wanted it to on his computer and I said quite innocently " I think your balls want a rub up."
We both fell about laughing because he said " At my b****y age you will be lucky to find them."
I couldn't see the screen on my computer with the tears of laughter rolling down my face.
