emails stopped working after update!

here’s the code I used to create a new form that revealed the problem to me

<p>Your Name (required)<br /> [text* your-name] </p>

<p>Your Email (required)<br /> [email* your-email] </p>

<p>Select Your Package (required)<br />
[select* package "--Select a package--" "Silver Package" "Gold Package" "Platinum Package"]</p>

<p>Tell me about your wedding<br />
    [textarea  your-message 10x3] </p>

<p>Enter the CAPTCHA Code:
[captchac captcha-587 bg:#666 size:m]
[captchar captcha-587]
</p>

<p>[submit "Send"]</p>

and here’s the css I had to write to make the email box show like the other fields

.wpcf7-email {
	border-style: solid;
	border-width: 1px;
	padding: 6px 8px;
	background-color: #FFFFFF;
	border-color: #E5E5E5;
	color: #999999!important;
	width: 100%;
}

how do you downgrade?
