Make sure you started your game from Age2_Albanian.exe and not the age2_x1.
If that's correct and still didn't solved the problem, then
Go to folder Albanian Civ Mod , then Games , then Albanian Civ Mod and you see 2 folders named data and Data. Delete the 'data' one and keep only 'Data'.
I don't know why are 2 there. I'm just the person tasked to upload and maintain the mod here on moddb
