Steinberg Xphrase Newbie Needs Help! Options

[purplezoid1]

Hello,
I purchased a brand new in the box copy of Steinbergs Xphraze from a dealer in the UK. I have installed it successfully but cant seem to open the player up. I can access the Xphraze folders> read me/license/content/installers etc. but whenever I go into the content folder and click on one of the combis/pads/riffs etc. I get a message saying "Thair is no default application specified to open the document" and am then asked to "choose application". I have no idea what application to choose at this point. Also, when I now try to launch cubase SX2 it stops at the Xphraze portion of the initialisation sying "Couldn't load Xphraze.dat please locate file manually" Then cubase shuts down on its own. I followed the simple install instructions to the letter. I wasn't asked for the serial number when installing. Has anyone got any idea as to what I am missing here? I have been to the Steinberg site and updated to xphraze 1.3 but this has made no difference, still cant open either Xphraze or Cubase SX2.... HELP ME PLEASE!!!
