Error on non-linear BNWF model/Opensees shuts down

[mapak]

Hello,

I am trying to model a non linear soil-shallow foundation system using the ShallowFoundationGen command but i keep getting the following error:
QzSimple2:: QzSimple2-- only accepts QzType of 1 or 2. Moreover the opensees.exe is shutting down so fast after that error that i couldn't actually see what the error was saying, and i had to video the whole thing and replay it frame by frame.
Initially i ran the same model for elastic analysis (footing condition tag=3) and there were no problems there. After i change the footing condition tag to 5 (or even 4 for that matter) the application keeps shutting down on me, and i cant seem to get it to work.
I think a couple other people have had the same problem http://opensees.berkeley.edu/community/ ... nwf#p60060
and there was a suggestion to use an older version of the program.
Is this the problem? Does anyone have any suggestions on these??
I dont even know if i can install and use an older version of the Opensees.exe with the newer version of the tcl interpeter.

Plz help anyone???
thanks
