WizaRd wroteDownloaded the game in couple hours, then I just never was able to log in.
Been trying every now and then since Saturday... oh well.
Wanted to see if it runs on this laptop before I buy it but I guess I wouldn't know...
Things you need to do to be able to login:
1- Switch the servers to "The Americas" and not "European". This can be done in the game menu on the character selection screen. When you select The Americas, click apply.
2- Enter your battlenet ID (email) and password but copy the password as well.
3- Press enter and wait 2 seconds, if it fails, press enter again, CTRL+V to paste your password and repeat.
You need to be fast on this because Blizzard limited the simultaneous connections allowed.
