Well, I fear you may not be here anymore after such unfriendly and wrong answers, but in case you lurk or someone else has this problem:
There is nothing illiegal about getting the PTW edit, you miss when having conquests. Just download the latest ptw patch from firaxis and unzip it in a folder that is NOT your ptw folder (e.g. c:\civptwedit). Then copy the two files Civ3XEdit.exe and CIV3XEDIT.HLP in your civ3ptw folder. Viola, there is the editor. Nothing illegal about that.
