I changed the password. I later logged out and then tried to Log In. Exact same error message as in my previous post (12:34 am).
For quite a while now (when I was able to log in), I have had to log in twice. The 1st time it says Incorrect Password. The second time, using the identical password, it lets me in. I had inquired about this when it first happened and I did not hear anything back. I just kept logging in twice - until this latest issue.
I have changed the password twice and this has not fixed the issue. Clearly with the dual log ins and the error message (which is incorrect - the username does exist) there is something else wrong.
