Help! We've got a NTU 1990 Coleman Newport. We got it about a month ago. We took it out camping once, everything worked fine. Just tried to open it in our driveway and my husband over cranked it. Doesn't seem like the cables snapped, but when we crank up or down, the crank just spins. There's no resistance. What could have happened? We aren't sure what to do or how to fix it. It's currently stuck in the 3/4 way up position but we put 2x8's (it's what we had) to hold the roof up so that we could get the door shut. Thank you so much!
