I can confirm that this is from GreekDDL Downloader.
I can provide some insight on what is happening as I am Greek myself and I knew the site that published that program.
So, greekddl.com used to be a very (very) popular Greek site (like ThePirateBay for Greeks) for pirating all kinds of stuff. Except from the illegal programs, movies etc. it also had almost every freeware's program new versions uploaded there. It was a very easy way to keep track of the new versions of programs.
It also had a very nice forum, the best Greek forum ever, in my opinion.
So, if I recall correctly, somebody begun reporting to Rapidshare and other file sharing sites about the pirate links available to those hosts. The corresponding hosts begun removing those links in order to avoid any copyright claims, I suppose.
Then GreekDDL hired a programmer to make a program based on JDownloader in order to download indirectly the links from the site. Basically you clicked on a button on the site and the links were added directly to your download section of the program.
Of course, the links could still be obtained from programs like Wireshark, but the reporters weren't so into tech and the reports stopped.
Eventually greekddl.com closed and became a news site that wasn't updated at all. Now it seems to be offline.
So, you won't be able to use that program but I doubt you would want to, because it was used directly for piracy.
PS: I was the one created the article you provided with your link, so the screenshot must be from my PC when greekddl was still up. Blame me for piracy :( You cannot prove anything :D Jokes aside, I was curious to see if I could still get that links through sniffing.
