Ive set new app specific password. when I go to Fix Problem on laptop the "enter passowrd" field is not there

I 'm not good at IT so help please!

I'm using a Toshiba laptop and NOT A MAC.

I want to use the Mail app o(the blue envelope)n my laptop to pick up mail from iCloud and Sky but am told that my settings are out of date. It says the same for my iCloud mail too.

I've gone to my Apple ID page and set up an app specific password but when I go back to the laptop field to "Fix account" the screen goes black with fields and instantly goes white then disappears.

How do I ( in "Janet & John language") solve my problems please.

Thanks in anticipation
