You have to follow the Links in post #1 and #2
Then put in the Captcha-Code at end of the page
Then you have to download the Link-Container (according to your Download-Manager, see next step), presented on the following page...
You need an Donwload-Manager for files hosted by Rapidshare, like the RSM-Manager from rapidshare.com itself, or Cryptload or jDownloader.
Load the Link-Container into the Download-Manager, then the download of RAR-Archives will be started, this will take several time...
You may have to use i.e. 7zip also, to extract the archives later (i.e. jDownloader do that for you, so you don't have to use an extra programm)
And notice the passwords in the post #1, which you need later to unpack.
