how do you open D-Lux 5 RWL files

I bought it from Authorized Leica dealer in Seoul Korea. I bought two or three Leicas from that dealer. But never bothered shooting in RAW mode before and never realized it was such a complicated deal to open the RAW file from DL5.

My question is how do you register DL5? I have a warranty card in which the Serial number is written. I went to leica.com and couldn't find any registration link.

I downloaded the Camera Raw and DNG converter both on my Win7 with adobe CS4 and on my Mac with Adobe CS2. The DNG Converter supposedly works fine. It quickly converts the RWL file into DNG. But when I try to open that file either on Photoshop or on Digital Photo Professional by Canon, none can open the DNG file. Photoshop says it is not a supported file type. DPP can't recognize the file type.

I don't understand why it has to be so complicated. I did download the right version of Camera raw and DNG Converter for my CS4. But for my CS2 on my Mac, adobe didn't release a version for Mac. Nonetheless, I downloaded the DNG Converter Version 7 and converted the RWL to DNG and hoped that either Photoshop of Digital Photo Professional must open the converted file. But it doesn't open.

My only chance now is to register the camera and get the link for the free software as I_ojectif mentioned. Please God help me if not Leica.
