So, yeah, here it is:
http://www.multiupload.com/0CTMEUCDVYRight now, as I'm writing this message, it's uploaded to both multiupload, depositfiles and soon also megaupload.
If any of you should have any doubts, here is a scan of the client: (link will be here as soon as virustotal is done. It will take some time because it's a very large file).
UPDATE: I've been trying to upload it to virustotal for more than 3 hours now, it's really slow. But yeah, I can assure you that it's the original file, so don't worry

But yeah, it's the official client, which I downloaded from the official website.
Hopefully this will be useful for you guys who have problems downloading from the original website due to the speed

By the way, on my internet connection the speed is about
500kb/sec when downloading from multiupload itself. So yeah, I'll highly recommend to download it directly from there.
