May be a stupid question, but was it a new CCT from Jaws?
I ask as it's not unknown for someone to buy a cheap one form the bay of fleas which then needs replacing after a short while.
I had a Jaws replacement around 6 years ago & it's still going strong.
May just need resetting. My knowledge of this is a little sketchy but there's what looks like a screw on the top of it which when you turn anti-clockwise, winds the tensioner rod in (I think). Wind it in then release it again, that may solve your problem.
I'm sure someone with more technical knowledge than me will be along soon to either confirm my thoughts or (more likely) tell you I don't know what I'm talking about.
