HELP: How to import reports from QReport made in D3 to D7

I used to develop in Delphi 3 but now I've purchased Delphi7 Studio Pro and
even thow all the reports work perfectly after compiled I can't open none of
the reports to make some changes. Any suggestion?
Thank's in advance.

P.S.: I've installed QReport Artist 5.1 and that doesn't allow me to open
the reports also.
