I had a look at mine and what had happened was the bracket that held the cable to the window mount had snapped off. It appeared that after a feeble attempt to repair the bracket to get me going again, the cable is simply under too much pressure for the design. We tried to reconnect it but there is no way a human could get the tension in the cable to stretch it enough to connect it. So, i have come to the conclusion that the machine that made the assembly simply had the tension too tight for the design.
