MX Simulator

I can't get the in-game editor to work, every time I try to add the "--editor" to the command line of the shortcut it comes up with a message box saying the following:
"The name "C:\Program Files\MX Simulator\mx.exe.exe --editor" specified in the Target box is not valid. Make sure the path and file name are correct."
Does anyone know what I can do to get the editor to work, I've had it working before on my old computer and it's frustrating me.

did you do "space" --editor in the "first" line.

Yes I have. Like I said, it worked on my last computer but I can't get it to work on this one.

download this it does it for you pretty much, http://forum.mxsimulator.com/viewtopic.php?f=1&t=11707

I was able to get it to work, just copy and pasted someone else's command line. Thanks though.
