I'm undoubtedly missing something simple and it's costing me time.
Here's the situation:
1) Document created in Excel.
2) Converted to PDF with Distiller.
3) Fields added in LiveCycle designer.
4) Reader rights added in Acrobat.
Now we discover that a phone number is wrong, and it appears that I must return to step 1 because I can't find a way to make minor text changes in Acrobat or LiveCycle once I have completed documents with rights enabled.
