What have you done before the problem was there?
I tried logging into the client but It kept crashing so I was confused. The server said online but the client wouldnt work since the Hoen region update. It turns out the the client needs to update however redownloading is impossible for mac. Check it. The download originates from mediafire.com however the Mac link shows up as "The file you attempted to download was determined to be dangerous. For your protection, MediaFire does not enable distribution of dangerous files."
