Notion3 Demo/Notion3 Musical Fonts

Greetings:
I'm new to this forum but had the Demo version during it's 14day trial period.
Looking forward to arrival of my Notion3 Order.
Had only one issue with the Demo if anyone can be of assistance:
I'm using Windows XP Home, SP3.
I don't know how it happened but the Musical fonts went south on me.
That is:
a. The note and clef symbols turned in to (?)marks and Note heads lost there note value and flag color
depending, Qtr.Half,8th,16th...........................
I was told it was a problem with my PC rather than Notion3.
That my "Font Cache" and or "The Jazz Font" internal to Notion were the problem.
Fond wise everything else on the PC is working correctly.
In advance:
Thanks
