Different Dell Docks?

I have a Inspiron m5030 laptop that came with Dell Dock. A while ago my computer completely frizzed out and would only work on safemode. After getting all of my important documents backed up on an external hard drive we reformatted my computer. During the process I lost the Dell Dock that was originally on my computer. I went to the site that you can download the dock and reinstalled it onto my laptop. I noticed right away that the Dell Dock is a completely different one from the one that was originally on my laptop. The original dell dock had large icons that were "Music, Video, Pictures, Books" and so on. The music icon would update to show the image of what song I listened to last. When the video icon was selected movies would appear that I could rent, and I could also go to my own videos and hulu from there.
When I reinstalled the dell dock from the website, it was completely different. I'm trying to find out how I can get the Dell Dock that was originally on my laptop! Help please!!
