Cable Stayed Bridge Non Linear Stagging Analysis (Backward/Forward) and some error in PDF tutorial

Hi COmmunity, I am using RM Bridge, But How to Model Cable Stayed Bridge including the stagging analysis calculating nonlinear effect, it is not very clear in the PDF file. If possible, could you give me the turtorial in English from you tube.

Second, the PDF tutorial given in the software is not really match/with the TCL file. Somehow it contains error.

I use RMV8i
