Room EQ Wizard V5.01 Beta 18 and 19 Released

just received this email telling me about the changes in the EQ Wizard. I know this has something to do with room equalization and I have used the microphone that has come with my Denon 311CI but I have no idea how to use the EQ Wizard. Is there anyone out there who knows how to explain this to someone with absolutely no knowledge on this? I would appreciate any help whatsoever. Unfortunately I would need the Wizard EQ for dummies version. I have a laptop. I think I am supposed to download this onto my laptop and somehow plug my laptop into my receiver? Is this correct? I just want to get the best sound out of room as possible. I have hardwood and 13 foot ceilings.

Thanks,
