Converting pdf file into a Illustrator or Photoshop file

Hi all,

Is there a way to convert a pdf file into an .ai or .psd file preserving all my layers that I had in my .ai and .psd file?

From Acrobat I did do a “Save As” a .eps file and when I open it and even “Place” it into Illustrator it groups the image into one layer and then sublayers. I would like all the graphic pieces on separate layers (as how my original file was). And/or is there any way to ungroup the image?

Any help or suggestions as to how I can covert the only file I have - which is my pdf file into a layered Illustrator or Photoshop file?

Thanks
