Bradley-Terry model as logistic regression

Hi,

I need your help. I want to use Bradley-Terry model as logistic regression (with intercept=0, x_ij=(1,-1)). I have only student version and the function genreg ist not avaible for me. 

I want to get the same results like there: http://support.sas.com/kb/24/992.html

 

When I have used the same datatable like in SAS-example (with y=win/total), the logreg didn't work. I tried also another structure of data:
jmp_1.pngBut it was also not helpful.

I have no idea, how the structure of data shuld be. 

I will be very thankful for your help
