Help Please: Retrospect Express 5.6 Restore Problem

Hi--Am hoping someone here can help me.  In 2004 I used Retrospect Express 5.6 by Dantz to backup the data from my old business.  It is now 7 years later and I need to restore those files to my Windows 7 laptop.  Can the latest version of Retrospect Express trial version help?  Does anyone have any other suggestions about what will make this data accessable to me once again? Thanks much in advance for your help.
