Client downloads for all campians??

Ya im one of those guys who wanna be a dervish but cant cause i dont have night fall and im really low on cash i found some places where u can download all of em but they dont work can ne1 help me out?

1 - avoid triple post.let the page load, even if its slowly, dun push submit button like a nut.

2 - it's a forum dedicated to gw, not a warez site.

3 - the client you download from official website and other websites, is for all campaigns.some areas download further.
but its the account who determinate wherever you can go.so if your account dont have a nighfall acces key allowing it go into nighfall you can dowload all you want you wont be able acces it,neva.

find yourself a acces allowing key to add to acc or cry.

The only place where you can "download all of them" is through Guildwars.com website. Download the client and you get the vast majority (not all) of the info needed in order to play any GW chapter.
In order to play a chapter, you need to unlock in your account with a access key. There is nothing else needed to download.
If a site is offering a download of all the GW games and it is not from Guildwars.com or official site supported by ANet or NCSoft..you are getting somehthing you dont want or nothing at all.

so i need to get another access key to play nightfall then?

yes.

each chapter is a retail different product.cant acces one you dun bough of the key.

so to play nightfall gotta buy nightfall and use key?

Yes.
Purchase NIghtfall. THen login and add the key to your account.
