Desperate

PLEASE HELP ME!

I cannot access my Yahoo! email account since July 19th, 2017. I am trying to unmerge it with my sbcglobal.net account. I get an error...

"Your AT&T account XXXX@sbcglobal.net is currently merged with your free Yahoo! account XXXX. You can continue to

use your Yahoo! account XXXXXX by clicking Unmerge. When you unmerge your accounts:"

However, when clicking unmerge - I get an error:

"Inactivity Timeout
Description: Too much time has passed without sending any data for document. "
