CSS Striping...No Style & WHMC Menu Widget Not Visible

Hey Guys! I hate to be a pest...but, in using the WHMCS plugin with my WP theme...it (almost) completely strips it of the WHMCS styling.

As an example, text is showing but, input fields, tables and buttons aren't visible.

Suppose there is some sort of conflicting code or am I going to have to style each element one by one?

Also, the WHMCS menu widget items aren't visible until logged in. Is this supposed to happen?

Thanks in advance!
