<p>I changed username (email address) on Wednesday.</p>
<p>After that, I cannot log in. Now I am so nervous and afraid. I should not change anything now. Regret What could I do to log in? </p>
<p>Sent questions to CA help center. They sent back several tickets but still not work now.</p>
<p>We almost finished CA and need edit to submit. </p>
<p>Please give a hand, please!</p>
<p>3 days passed, so stressful now </p>
