Installer Issues

[Lidenbok]

So I started installing today after getting my invitation.

The issue I have its rather random but occasionaly my download will just close, no error nothing just disappear off my screen.. any thoughts? I have tried searching but all the results I get are to do with errors and stuff like that.

If installing on Vista make sure you run as administrator, just to be sure. Also, check the official forums and make sure your firewall is disabled or at least lets WoW access certain ports. Without an error, though, it is impossible to know exactly what the problem is.

Turnt all firewalls all, running as admin and this is an admin user account.

No idea what the issue is :<
