Hello everyone, i seem to have a problem here. I found this game on steam when it was 10% off, and was very intrigued. Upon closer look, it reminded me a lot of the total war series(which i like a lot), but potentially better. So yesterday, i decided to buy the game, and i was not disappointed. Though initially hard, i find that it is easily on my top 5 games of all time. however, it does have it flaws. When searching the forums, i found out about Hegemony Gold, and i was excited about it. I decided to download it, but then i ran into a problem. It says that Gold is only a demo, so i can only do Philips campaign. I tried my serial code that i got with Hegemony:Philip of Macedon, but i keep getting a "your serial code is not valid". Any help would be very much appreciated.
