My Acrobat DC (Order number: ADD030792008BR) close immediately a few seconds after opening in my notebook and also in my PC. Moreover, if I try to use it, it stands open only a few seconds. Also, I can not print any document with my Adobe pdf printer. So, I have bought a program that I cannot use. Fortunately I did not uninstalled Acrobat 11 Pro!. What can I do? I did not installed Acrobat DC corectly? My PC is a DELL Precision Tower 3620 and my notebook is a DELL Precision M1400. All my other programs work fine. Can you tell me what happened or can I have my payment back. Enclosed you find my purchase confirmation. My e-mail address is georisk.plus@live.com. Thank you for your attention, because I am in trouble. Franciss
