Where is the Editor in TA5?

[Shephren]

Yeah,finaly it works without crashing.But,if i want to open a map,he minimizes to give me the chance to choose a map,first the file type is .SAV,i've got to change it to all files to see map files,but he doesn't want to open them.Nothing seems to happen.Futhermore i've got to copy the map i want to edit somewhere else,because if i launch the editor,or FE,the folder missions in FEaddon is emtpy.
Sry for being so dumb concerning the editor...anyway,thanks to all of you for your guidance.

Edit: But what should i save?I mean, i can't open a new map,or an existing one.Just the ones i've got in Instant mode,and that's not what i want.

if the file type is a .sav it means youre not saving it properly.

you have to save with editor mode enabled, and use either CTRL+S or press the save button in the EDITOR window, NOT the escape menu.

don't mess with .sav just select "all files" and open the .bzn files
