Bladerunner compound bow

I have a bladerunner ISO - force compound bow.
The string needed replacing, I took the string off and made a new string the exact same length.
When I tried to replace the string it was to long, and can not work out how to replace it. It seems that it can only go on one way. All the Internet information gained shows all the cams in the right place, but I am obviously doing something wrong!
can anybody with a bladerunner help?
