You can carry on using your version of pro after the six months for as long as you like and it will always have the pro connectivity. You will no longer be able to get pro support, or update to a later pro model.

It is worht noting that the CD is really supplied as an second best option to downloading from limewire.com when you are assured of getting the latest version

I hope this answers your question.
