Can't merge data files into spreadsheet on secured document
i created form in acrobat x pro. form secured first using password restrict editing, allowing fillin form fields. enabled file saving enable addtional features, , save file. works ok: can't edit form , allows me save it, when use merge data files spreadsheet export data, exported csv file empty. can't export data. tried remove password protection got following message: you cannot change security on document because document signed or certified. is there can fix this? either been able export data or removing protection. thank you. the next time add security, select "enable copying of text, images, , other content" option if want able export form data. as is, should able "file > save copy" , remove security.
