Nostalrius Begins - Quality wow vanilla realm (1.12)

Been playing for weeks now, never had this problem before, tried for the last 2-3 days to login, no luck.

Tried logging in peak time at first, thought it might be because of the 12k+ players, now i can't even log into the PvE server aswell, tried logging in on off-peak time, same drama.

Anyone else having this problem aswell? Tried everything I can think of, tried the tech help guide etc.

Anyone got any ideas?

Thanks.
