I have sent an email, which you have replied to. As I am in Australia I was in bed at the time. I will double check the information you gave me and try and troubleshoot after work today.

So I have managed to mount it with everything moving pretty freely, however it seems to not be loading and unloading properly.

As you look at the box with the switch connection at the top double check that the left side motor connection on connected to the left motor and vice versa. If that doesn't fix it I am unsure and it's definitely for bill to inform.

I took the screws out and did it manually which freed it, put back together and was fine then it froze again so I tried the same process but this time it has now stopped working all together. I will try again in the morning.

Ok I will give that a go and let you

I noticed the green light is flashing in the control box. I had that happen when the motor cables were not plugged in the correct side in the box

The sliding components are stuck and do not want to move. I haven't forced it much as I didn't want to possibly damage
