I have already reset my password via the 'Forgot my password' function, confirmed password reset, and confirmed that I am entering the new password. PSE 10 still gives me an 'Invalid email or password' message every time.
Are you getting the error while installing and doing the sign in process?
to confirm that the adobe id is working fine, please go to www.adobe.com and then try sign in in the account and chek its working fine or not.
If you are facing anyother issue then share the screenshot of the same.
