Since Mangastream don't provide download links to their manga anymore and you cannot right click and save the images manually i have decided to create this thread to help people. (not sure if this is in right section) You can download the program here:
http://www.megaupload.com/?d=011QA1XQ How to Use: Clicks on the option that says 'Add all ms manga' >! You will now have a list of manga in the drop down menu
!
Choose the manga and chapter you want to download
!
Click download. You can see the progress at the bottom
!
You have now downloaded effortlessly from MS. The chapter will be located where you set your directory (mine is desktop) which can be changed.
!
P.S. I think you need Java installed to run the program and winrar to extract the archive.
