The website is working for me on Safari, v7:

Note that the old site (http://www.qpcard.se) does not work.
You can download and install the latest version for mac - according to the website:
Current version is v1.21. This update contains new cameras since v1.20 and an OSX Mavericks compatibility patch
A year+ ago when I first purchased a Fuji X100 and tried it with the QP202, the profile was written with the incorrect camera model identifier and LR/ACR did not read the DCP and include it in the drop down list of profiles - I did the same thing as Erik mentioned above (dcptool) and replaced the incorrect xml and it worked fine. I sent a bug report to QP and it works fine now. If you find that your QP camera profiles are having a similar issue, you can use dcptool to decompile a correctly working profile and check what is inside the xml:
<UniqueCameraModelRestriction>Canon EOS 5D Mark II</UniqueCameraModelRestriction>
where the canon 5DII verbiage is shown for a DCP profile above, for example. Decompile your non-recognized QP profile to see if the identifier is not identical to the working DCP identifier - if it is not, replace it and recompile and it should work. Report it to QP!
