Editing protected (NO SAVE AS) PDF... can PRINT to save form data, however when try to SAVE AS PDF get message need ACROBAT PRO to save PDF... upgrade to FREE TRIAL of PRO and still can't save PDF file. Attempt to EXPORT AS DOCX or PDF and same error message, require Acrobat Pro. It appears that ACROBAT READER is not refreshing license to understand TRAIL of PRO enabled and as result, does not allow all features. I am stuck... I can't save file and results in DATA LOSS. Adobe needs to fix READER so that license changes updated in running product. There should be an option to refresh license, as example... this would avoid issues.
