So... Installed the game.
1st time in loading screen... game freezes at 10/15%.
I delete chache, WTF and Interface folders. Launch Firestorm and game itself with adminstrator privileges > loading screen freezes at 90%. Ridiculous. Ah! Tried the unstuck character too but since it's my 1st login EVER ... Ridiculous again...
I wonder how the game would load with Addons activated LOL
2nd attempt > finally I got to the cutscene... pressed Yes to cancel... Screen goes black and after a while "Error on bla bla bla stream. Blizzard bla bla bla xxx 322".
3th attempt > Loading screen freezes at 60%.
4th attempt > Loading screen freezes at 60%
5th attempt > IT'S A WIN! LOL
