Hello and Thanks for replied me.
I Had Just one version installed when I posted this here. CS6
So I think the version isn't the problem..
I have noticed couples of things when right clicking a (*.swf) file and choose open with ADODE Flash CS6.
1: it's say preparing to import! shouldn't have to import the (*.swf) file.
But Just Open it.
2: From File>>Open>>Window: from the drop down menu at the right bottom, there should be a option to open SWF Movie(*.swf).
For Flash CS6, there isn't a option to chooce that.
it's there for Flash CS5.5
You can still choose All Files (*.) But again from there it still trying to Import the SWF like it was handle a .FLA file.
Hope I have given you a clean explanation of what I am seeing.
English is not my native language, so I try my best to make it all understandable.
