@Paul: I see that there is problem with the Email field. We will fix this in new version update. For now you can add the following css in “Appearance => Theme Options => Custom CSS” box. 
input[type="text"],
input[type="email"],
input[type="url"],
input[type="password"],
input[type="search"],
textarea {
	color: #666;
	border: 1px solid #ccc;
	border-radius: 3px;
}
input[type="text"]:focus,
input[type="email"]:focus,
input[type="url"]:focus,
input[type="password"]:focus,
input[type="search"]:focus,
textarea:focus {
	color: #111;
}
input[type="text"],
input[type="email"],
input[type="url"],
input[type="password"],
input[type="search"] {
	padding: 3px;
}
@media screen and (max-width: 767px) {
	input[type="text"],
	input[type="email"],
	input[type="url"],
	input[type="password"] {
		width: 80%;
	}	
}
@media screen and (max-width: 320px) {
	input[type="text"],
	input[type="email"],
	input[type="url"],
	input[type="password"] {
		width: 98%;
	}		
}
Note: Remove this after you update to new version coming soon.
