Thanks for your welcome, and your answer of course! Well, I've copied and pasted the content of the file linked in my previous post in the mod folder, then I've just started the game and automatically it loaded the mod. After that I've started playing, reaching the requirements to accomplish the II phase,but once entered in the phase I've seen that barraks, temple, market and CC were still gray, with the wording "Requirements: II Phase". Maybe, as you said, it's some kind of incompatibility with the Alpha 18. Just to say, I've also tried the Rise of the East mod, which goes without troubles. Thanks again for your help and attention!
