Ihate7474 on "Question about Becker 2013 Software"

Hi everyone,
I just purchased the Becker 2013 software. I am not sure how many times can I download the software to my desktop. I know I can always log in to the online course, but I prefer download the software in case I lose the internet connection sometime. In addition, Can my two computers open the software at the same time? Thanks for helping.
