Hello SE, I need help ASAP pls.

I had to do a complete format of my PC & clean Windows 7 64bits reinstall.

Now I'm not able to launch the game or even log to any SE webs (doing it from my work PC now).

I can start FFXIVsetup.exe normally, it installs the launcher, but when I try to open the "Final Fantasy - A Realm Reborn" icon all i get is this message: "A system error has ocurred -21669711"

Not only that, I'm not able to reach any of SE websites, neither na.finalfantasyxiv.com or support.na.square-enix.com or secure.square-enix.com/account
All of them give me a "error connection timed out" answer.

Only SE webs, every other web I try to load (youtube, facebook, twitter, whatever) works perfectly.

I've also tryed using a proxy.
With a proxy I can reach SE webs but I still can't get the launcher to work, I get "Unable to Complete Version Check [30605][20448][10009][10019]"

Again, PC has been formated clean, so there's no malware, anti-virus or anything blocking my connection.

I need help ASAP.
