Changing reports from QR 2.0 to QR 3.0

Hi Everybody

I'm upgrading from Delphi 3 to Delphi 4 and all of my reports didn't works
when I tried to execute then. I know that I have to make some changes in the
reports source but I don't remember what.
If someone could help me I'll be glad.
Best regards.
