It appears that Primalfont (v. 0.0, Feb. 2003) is not installed on your computer. You must install this font to view the Tutorial correctly. The new Primalfont eliminates many of the problems of the old Primalscript:
If you had previously installed the old Primalscript font, go into your Fonts folder and delete the old font first. It will be listed in the Fonts folder as Primalscript or PRIMALSC.TTF.
To install Primalfont, right-click here and select "Save Target As..." Then, locate the Fonts folder on your computer, probably in C://Windows/Fonts/ for Windows, or System Folder for Macs, and save the file there.
If this doesn't work, try the following: open the font file manually, right-click the file and select "Install", and reboot your computer. Most users experience no problems installing a TrueType font, but occasionally someone will have trouble. If you have any difficulty with this, please email me and I'll see if I can help troubleshoot.
Once you have installed the font, click here (and refresh the page) to see if it worked.
