Hi Hector, You must go to Tools > Additional File Tasks and copy the missing files. Regarding the differences between reaction approaches, this is probably because the gibbs formation-based K expression is not adequate for this reaction, otherwise the results would be the same as in the "Gibbs and Equilibrium Reactors" sample.
