Antigonid Mod not showing in mod list

[billb]

I downloaded the Antigonid Mod from Steam. All folders appear in My Games/Sid Meiers civilization 5/mods/Antigonid Dynasty (v. 2). The "Art, Lua, Modcompatability, Music, SQL, XMl" folders and credit.txt, Antigonid Dynasty (v2) mod info files are all listed in the folder. These are all the items listed in the .civ5mod zipped file. The mod used to appear in the mod list before I changed computers. What do I need to do to get the mod to appear in the mod listing so that I can activate it? My apologies if this has been answered before. I tried searching for an answer, but was unable to find one.
