Hi, I can't login my Apple ID on the mac app store.

Currently, I'm using Lion and want to upgrade to Mountain Lion but like I said, I can't login.
I'm 100% that it's a correct password and everything, I can login on iTunes but not App Store.

It says "An unknown error has occurred"

Anyone know how to fix this?
