How to calculate band diagram of my photonic crystal structure with BandSOLVE?

Hi everybody

i want to calculate band diagram of my photonic crystal structure with bandsolve
but i cant?

I think it is about my software!!!!!!!!
does anybody have this software to send me?

thanks for your help

there is a software in MIT photonic band gap, (MPB) package is a free program for computing the band structures (dispersion relations) and electromagnetic modes of periodic dielectric structures, on both serial and parallel computers. It was developed by Steven G. Johnson at MIT along with the Joannopoulos Ab Initio Physics group.
