Saving the fillable form in Acrobat 9 Reader

Issue: How do I get the Acrobat 9 Reader user to be able to edit a fillable form then save and reopen the same form and save again?

Method:

Using Adobe Acrobat 9 Professional I made some comments/markup -> SAVE

Using Adobe LiveCycle Designer 8.2 I added some objects -> SAVE

Results:

When opening the file using Acrobat Professional 9, I can "Save" and "Save As". Everything seem OK.

When opening the file using Adobe Acrobat 9 Reader, users are not able to edit the fillable form.

I've gone Advanced -> Extend Features to Acrobat 9 Reader from Acrobat 9 Professional. I still wasn't able to save on the Reader.

How do I get the Acrobat 9 Reader user to be able to edit a fillable pdf and save it to the hard drive and update the file multiple times?
