When i download a map from the UGX Map Manager in the map's folder there is 2 files named "mpdata" and "mpdatabk0000" and when i launch the map through the UGX Map Manager it starts CoDWaW normally then brings me to the mod list and there is nothing there but gives me the option to "Launch" or "Launch without mods" but won't allow me to click Launch. Everything else is fine though. Anyway to fix?

I already answered this...

If theres no mods in the list, then there "are" no mods "to" launch - which is why the button is greyed out

the "only thing you can launch" is without mods, hence why that button you "can" select

Your mods are not installing for whatever reason, they should be installed into the call of duty folder in your APPDATA folder

But the maps are downloading to the APPDATA folder

then they should show in the call of dutys in game list

show us a picture of the mods in the app data folder

But the maps are downloading to the APPDATA folder

go to the update folder and take a pic of it and show it to us

Steam just did an update I'm able to launch the maps. Thank you all for helping me through my problem!

interesting... as the two are not related other than steam must be on to start the game...

but glad you got it sorted

I am having the same problem but steam updating fixes nothing...

me too
