Boxster rooftop opening and closing

[wams]

I have a 2002 Boxster 2.7L. The rear plastic window was torn and took it to get repaired, along with minor body paint. The body shop sent the car to a car upholstery shop to have the rear window repaired. Instead of just repairing the window, the upholstery shop replaced the whole top canvas (with the plastic window)! Before the car was given for repair, the roof went up and down without any issue and I could also close it with ease. When I got the car back, I was told not to lift up or open the roof for the next 2 weeks, for the roof to settle in. I waited for 3 weeks and tried to lift the roof. The magical light on the console for the roof release would not come on, meaning that the emergency switch for roof opening by the handbrake (inside) was not working properly. I replaced the switch and the light would light up on the console. I tried to lift the roof, it was making a whole lot of noise and finally the roof was off and settled in the back where it is supposed. I tried to put the roof back and again heard lots of grinding noise, sorta. I was able to close the roof. I found that the tensioner cable (I think that’s what it is called) on the passenger side was off the track and was hanging outside, overlapping the frame, was very tight. Since then the roof, after the inside latch is released, only lifts the roof about 2 inched from the front. The back frame does not even lift up like in service mode. I need some help in understanding what could have caused this to happen. After a new canvas top in placed:

1.) Is there a need to re-calibrate the transmissions on both sides?

2.) Could the upholstery shop mess up the roof lifting mechanism?

It is very unlikely that the emergency switch was not working. I tested the original, one that I took out, with an OHM meter and connectivity of the switch was working fine. It is coincidental that the roof lifting transmission and the cable, etc. were busted when the window was repaired! I will appreciate you any or all feedback with what could have made this to go wrong, especially, when the tensioner cable went off the track and was hanging over the passenger side. [if I remember correctly, then a Porsche dealer fixed/replaced parts for the rooftop lifting mechanism in 2010.] Thanks.
