Ok,I think I got it!I redowloaded DFW again,then after installing,I looked in the FSDreamteam/Couatl folder.The Couatl.application file was gone,replaced with a new Couatl.exe. file.Its like the file wasnt opening on installation.I copied and pasted a COuatl.application file I had saved in another folder.I then started FSX,noticed that now,both application manager and couatl program files were there.Went to DFW,and YAY!There it was .And it was certainly worth all the trouble.Fantastic scenery.Thanks for the help.
