Okay folks, problem solved. :)

This is what solved the problem for me:

.enews-widget input {
     float: left;
     margin-bottom: 1.6rem;
     margin-right: 5px;
     width: 68%
}

.enews-widget #subbox1 {
    float: left;
    margin-bottom: 1.6rem;
    margin-right: 5px;
    width: 100%
}

.enews-widget input[type="submit"] {
     display: block;
     float: right;
     margin: auto;
     width: 28%;
}

Cheers,
Mark
