I'm trying to teach myself the Structural Steel modeler and I have walked through a couple of the examples in the user manual. Only problem I'm having is saving the files. I have saved example 2 as a .c2s file, but I cannot open it. It seems to be a bit more cumbersome with regards to saving files and analyzing them. Any words of wisdom on this would be appreciated.

Also is it true that the latest steel code it references is AISC 1989? Is there a way to get a more updated code?

Thanks,
Lisa K.
