Which version of FairUse4WM should i use?

[themen]

I want to watch a movie that i bought from a site with another computer but i can't, a login page pop up requiring me to input the login and password when i play the movie, however i delete the account already once i purchased and downloaded the file. I am still able to play the movie in this computer (Window XP, WMP 11.0.5721.5280) without logging in any site.

I find there are many version and update for FairUse4WM, but i can't find any update for the tutorial, for example, the tutorial still teachs the users to downgrade to WMP 10 and dealing with Napster even there is FairUse4WM compatible with WMP 11, so i don't know whether i should to downgrade my WMP or not?

My question are
1.) which version of FairUse4WM should i use to remove the DRM?
2.) is there any up-to-date step-by-step tutorial? (i don't want to follow a instruction that tells me to downgrade to 10 when the version is already compatible to WMP 11 final)

I appreciate anyone helps, many thanks.
