Windows Media Player - Media Usage Rights Acquisition - Once or Always

I subscribed to an instructional poker website that has videos. If I download them, Windows Media Player brings up Media Usage Rights Acquisition which asks me for my username and password for the website. I type those in, and it says License Issued and allows me to play the video.

I'm worried by this. If I subscribe to a magazine, I can keep the magazines and read them later. I'm worried that's not going to work this way in this situation.

QUESTION 1 - If I stop the subscription in the future, can I still play videos that I already played? Or, does it check if the license is still active each time it's played -- so in the future, it could say that my subscription isn't valid, and disallow me from playing the videos?

QUESTION 2 - If I back up the license files through License Management, and in the future I purchase a new computer or reformat this existing one, can I always restore the license files -- even if at that point in the future my subscription is no longer active? I figure there must be some sort of catch here, or else everyone could circumvent the license management by distributing the license backup file.

Thanks! With those settings off, it does complain about a file not already played, asking permission to get a license -- as expected. But with those settings off with an already licensed file, it just plays without asking any permission... So looks like you solved my question 1, allowing me to play the files in the future without a continuing subscription if I choose to do so.
