I just bought one year Acrobat Pro for using on my MacBook Pro retina (MacOsSierra version 10.12.3) after many asks for buying it, and now when I open any document of work it kind collapse with an critical error. I've paid $14,99 US dollars apparently for nothing. Please help me! Before buying it, I tried to uninstall it without success. Its very frustrating indeed to pay for nothing. Hope somebody can help me on this awful trouble. Thank you in advance.
