Troble saving a file in eDrawing format

Hi

I have updated my SW to 2012 a month ago and since then I have used eDrawing for a dozen times with no problem. Today, after I tryied to save a part  using "Publish with eDrawing", the eDrawing pops out with a blank screen. The file that was saved as an eDwg, can not be open neighter on my computer nor in others. Any idea what can be wrong?

Thank you.
