I have tried both versions and I am no longer able to print any PDF files. The programs open and close properly. Every funciton seems to go flawlessly. The printer will engage, the queue will list the job for about two seconds then nothing. No lock up, error messages, nothing. Am able to print anything else from any other program, before and after the attempt. This is the same on both my personal(home) and work printers. Both are HP printers. Any help will be appreciated as I deal with PDF files all the time. Thanks.
