Well, I did a clean install of fourDeltaOne to another folder.

The folder I installed to:

C:\Program Files (x86)\Steam\steamapps\common\fourDeltaOne

When I play fourDeltaOne with the LaunchIW4M from the folder above, configs and demos saves to the following folder:

C:\Program Files (x86)\Steam\steamapps\common\call of duty modern warfare 2

Whattodo, I also happen to experience 17, 19, 34 and 42 in Toolbox's thread.

Worked perfectly before I reinstalled Windows.

EDIT: Moved the folder, no problems so far! Thanks.

Ok, you got it fixed. Also the installation doesn't work when you move the folder, so you go to the localappdata, delete IW4M and the reinstall it using our installer.
