The bit.ly links for black and blue give an error at the moment.
Thanks for reporting.
Interesting, but I have no explanation why there is some security warning specifically for the URLs of these two colour variations only.
The links are simply referrals to my Dropbox repository, same as all my other skins and other contributions.
I'm guessing something is going on at bit.ly that must be affecting many other people too.
All I can (will) do for now is wait and see what happens in the next couple of days.
I took a look to see if I could report this to bit.ly from my account, but they provide no service at all for me to do so.
It looks like only people using the link can report false security blocking done by bit.ly.
So it might help if people that like to download these skins would report the false security block to them.
(and Void Green is the best one in the series anyway and that's still available, so I'm not too concerned yet ;-)
