So hello People, i've researched the Internet for Fixes of multiple Errors, thankfully i have fixed all expect one Error ;

Moving   D:\OYUNLAR\Call of Duty World at War\Call of Duty - World at War\zone\english\Testv3.ff
    to   D:\OYUNLAR\Call of Duty World at War\Call of Duty - World at War\mods\Testv3\Testv3.ff
Copying  D:\OYUNLAR\Call of Duty World at War\Call of Duty - World at War\mods\Testv3\testv3.ff
     to  C:\Users\DENİZ\AppData\Local\Activision\CodWaW\mods\Testv3\testv3.ff

I really don't know why this happens, i have tried deleting the folders in the "maps" Directory, have changed the Option of my CoD WaW root folder "read only" , i deactivated that but still there is that one silly Error which really annoys me. Feel free to also post some very basic Tips about Mapping as I just started mapping yesterday.

Try using a diff script placer, it might not fix it for you but its worth a try

Ooooooooooooh just keep spamming codwaw.exe by that i mean click it like 10 20 times tell your codwaw window opens.  That should fix it.

Just try and launch the game manually and load the mod in the main menu instead of using the option in launcher

I tried launching it normal in the main menu but it still didn't work. 

Uncheck "run map after compile".
Then compile map, patch, then mod and play.

What do you mean by patch? How should i patch it?

If you dont know about this stuff i suggest looking at a few tutorials, it's really the basics

Ohh, that, well i already did that.
