i have 2 yahoo accounts, but for some reason i can log in and check my email in only 1 account. the other one, i can log in, but i can't check my email. when i click to check my mail, it does nothing or it says "page cannot be displayed." but it's like that for only one of my accounts. i even tried changing my password, but that still didn't resolve the problem. i also tried checking my email from 2 other computers, and the same thing kept happening. what do i do? how do i access my email?
