I've been using Livecycle for years and I've always opened up certain documents made on LiveCycle and I've edited the text, field boxes, etc. All of a sudden, I go to edit a PDF in LiveCycle (same PDF that I've always edited) and everything is locked. I can't delete, add text, move fields, nothing... It seems that the whole page got locked somehow. Does anyone have any ideas on how to get it back to normal so that I can make edits? I'm using Windows Vista, Adobe Acrobat 8- LiveCycle Designer 8.0.
