Ok, I recognised that Mediafire sucks.
It blocks nearly half of the links, for some shitty Copyright reasons...
So I decided to re-upload all the not working links on zippyshare.
I hope it works fine now.
For the future, if anything's not working, a link is dead, or whatever - dont wait to tell me!
Write me an e-mail, make a comment, come by, ... ;-)
