I have the Steam Version, I have found the mod files but they still never load up. I am honestly confused to how the map files are there but then they never load.

I have tried to play 5 different maps but every time I go to try to play them, the never load. When I try to find the files to the maps C:\Users\<USERNAME>\AppData\Local\Activision\CoDWaW\mods
its not existent, how do I get that/make the maps work.
 

I load up the Map loader and then it says, "Invalid Internet Connection" I have unplugged my Ethernet Cable and plugged it back in and nothing seems to work I cant get it to work at all, I have uninstalled it 15 times and yesterday it was working just fine, can you please explain what is going on because this is ridiculous. I have also checked to see if the UGX map loader was down but its not.
