Check that :
-before re-installing ECP, you delete if it exists the @ECP folder inside your OFP/CWA directory , so it re-installs cleanly.
-make sure when re-installing that you're using
Code:
ECP v1.085 (Full Installer).exe
The one you get by example from that OFP.info link
Install with disabling any option of the installer.
- once re-installed , check in your OFP/CWA directory that the ECP mod folder is named -exactly-
And not named anything else, some mods need their mod folder name to stay exactly what they are by default, changing them would break the mod.
- The full install of the ECP mod has the whole @ECP mod folder being roughly 170 mo, check that it is the case
-The @ECP folder have a subfolder named
and inside of it, the following files are all there.

-Use an OFP/CWA shortcut with
Code:
-nosplash -mod=@ECP
command lines added to its target line
Does it work ?
If it works, now get the ECP patch 1.085e :
http://operationflashpoint.filefront...CP_Patch;70121
The patch is just the file named ECP_Effects.pbo
that youwill replace with the original one from @ECP\Addons\
And finally, go to @ECP\bin\ and open the config.cpp with a text editor.
somewhere near the start of that file,
Replace
Code:
// PBO release path
#define ECP_FOUNTAIN_EH_INIT "IF (format[{%1},ECP_path] == {scalar bool array string 0xfcffffef}) THEN {ECP_path = {\ECP_Effects\}};_this exec format[{%1fountain\ext_fount_init.sqs},ECP_path]"
by
Code:
// PBO release path
#define ECP_FOUNTAIN_EH_INIT "IF (format[{%1},ECP_path] == {scalar bool array string 0xfcffffef}) THEN {ECP_path = {\ECP_Effects\}};if ((typeof (_this select 0)) in [{Fountain},{FountainNew}]) then {_this exec format[{%1fountain\ext_fount_init.sqs},ECP_path]}"
to fix a bug related to the fountains.
Save the changes, make sure your file is always named config.cpp and not config.cpp.txt or something like that.
