New Release: MUIO v5.6 for OSeMOSYS is here!

Hi Fernando,

I am unable to run any of my models in this latest version. I do everything as on the course but keep receiving this error message:

Warning! Presolve determined that the problem was infeasible with tolerance of 1e-008 - Total time (CPU seconds): 0.22 (Wallclock seconds): 0.22

Can you please assist?
