I visited the website linked above. While I was able to listen to the demo, the soundset does not appear to be available for sale anymore, at least it doesn't show up in the webshop for me (U.S.).

Found an older thread here from circa 2005 that indicated a Tiesto soundset that mistakenly shipped on an official CD from Access, but was withdrawn after an update. Not sure if it is the same soundset in question.

Where did you get the soundset you are referring to? If it is a commerical soundset, and you did not purchase it directly, or perhaps downloaded it from a file sharing site or something, then I am not surprised it doesn't sound correct. If you purchased it from freefloat, I would contact them for support.
