It seems that adobe has problem with signing to Adobe account. After several attempts to login, when I was receiving
"The Adobe ID and/or password provided does not appear to be valid. Please try again."
I tried to reset password. However I got error
"The provided email address could not be matched to an account on file. Please try again."
Adobe helpline responded that “I am sorry to inform you that there is a login problem going on with our website. Our web team is working on it. Please wait for 2 to 3 hours. You will be able to login.”.
