Whenever I try to login to World of Minecraft I get the error "Unable to authenticate. Your username/password may be incorrect or there are no servers available to validate your login." I know that my username and password is correct, so what's the problem?

I got this message too after I tried to log in when I upgraded my minecraft account. I sovled the problem by clicking valid off :P
It is nearly impossible to know what is wrong dude, sorry.
