Just want to sum it up for all. In order for this to work, you need two things, that is:

1. Rapidshare or Megaupload account
2. A download manager ( I prefer IDM)

First of all, using IDM,

You can view it here for rapidshare user or here for megaupload user

for those using flash get,

view it here for download multiple megaupload file using flash get and here for instruction with picture.

Now, for bonus question, how do i get premium rapidshare account?

well either you buy one or read this.

Hope this post will guide you to right direction.
