[OS] CPLEX Error 1017: Not available for mixed-integer programs.

Hi Joe:

I am not familiar with Google files section. Could you attach and send 
to my Chicago email.

I am going to be in a meeting all day and also don't have any access to 
Cplex but I will see if I can figure out what is going on.

Cheers,
