For the past few days WLM 2012 will not allow me to sign into either of my email addresses that I use on this platform.

I get an error message that either the email address or password is incorrect. So I reloaded one of the email addresses. It repopulated, but I still cannot sign in. And once I reloaded it, I could no longer receive email in the 2nd email address. I tried reloading the 2nd one, but it will not populate my files or any email, & will also not allow me to sign into that account. Same error message. I don't know what to do. I saw a similar question regarding a Gmail account on WLM, but the answer doesn't apply to me. Please help!
