I have lexi-complete, but I don't know anything about a CD though. Since nobody has replied yet, I will just post my experience with lexi-comp. When I first downloaded the software from the website, I had to register my pc and pocket pc using an ID number shown in my pocket pc after the downloading process. I entered that ID on their website (in my account) for each book I purchased.
I am guessing you will get a different ID number for each device since there is not an extra blank to fill in more than one ID for each book, so I don't think we can load the software to multiple accounts. I know it is very confusing...😕
I do know that if you do not renew your subscription, you still get to keep the books you have, you just cannot get the files updated. I hope this information is somewhat helpful.
