I use LiveCycle Designer ES Version 8.2.1.3144.1 (CS4). Operating on Windows 7 64 bit. Have used LC with no issues until today when it will not open pdf files which are not corrupt and opened perfectly many times previously as recently as a couple weeks ago. No changes to computer or program have been made. Have tried opening multiple pdf files (all which previously opened fine and which I was able to edit in LC with no issues) and get an error pop up window reporting that program will not open... no solutions to problem suggested.
Does anyone have any idea what may have happened?
Thank you.
