So, I try load up maps by zombiemodding.com and here at ugx-mods.com they just dont load up the map right!  Please help solve this issue, the maps show up in my mods folder and can be loaded when I hit Launch, but Co-op or solo dont work....

Sorry this is late, but the way you worded it was very vague. If you see this post a reply specifying the issue, but for now I can tell you this:

Make sure you Build the map first with everything on the right, "Build IWD" and "Build mod.ff Fastfile" checked.

Then compile your map with everything but "Compile Vis" checked. ("Running the map after compile" is optional.)
also make sure your map's mod is selected in the list at the top right

Then compile your map's PATCH with NOTHING checked except for "build fastfiles" and "Mod specific map"
once again make sure your maps mod is selected in the list.

Make sure at the end of each and every one of these processes it does NOT say "Error ####" at the bottom right.

If you did this correctly, and your map has something in it, it SHOULD run. And remember, launch the map through CoDWaW. I don't know what you mean by launched it through the website
