Hey guys, Twice a year, I edit a journal that is ultimately produced as a .pdf file by the graphic designer. She converts it from Word to Acrobat, then sends it to me for the final edit before sending it to press. In the past, I've downloaded a temporary version of Adobe Acrobat Professional, from Adobe, so that I can make the final edits on the .pdf and send it back to her. I'm having a major error this time. When I download Adobe and install it, the files won't open. Acrobat won't open, my .pdf won't open. No error message or anything, I double-click the item, it gives my cursor the "working hourglass" for two seconds, then nothing. Neither file will open. Adobe simply won't open. Does anybody have any ideas? Everything else on the computer is working fine, I have enough RAM, no AV software to block it. I've restarted, reinstalled, uninstalled, blah blah blah. Thank you guys!
