<p>I would love to know how to retrieve the link 'http://dc109.4shared.com/img/1038702204/8ffe01b/dlink__2Fdownload_2FxAdbDSb4_3Ftsid_3D20111224-60034-aa918a50/preview.mp3'.</p>

<p>I asked around other forums and people numerous times but I still do not understand/not working.</p>

<p>It is a must that I get it through class "show1" as there are other classes.</p>
