Ok I've figured what Mac is talking about, remember we got 2 CDs right.
The textbook has a CD inside it and there is a UNISA CD as well!! use the UNISA CD instead then you wont have the ".hqx" nonesence . Inside the CD you will see a folder called "Masterskill", open it and you will see a bunch of ".exe" files (Install-CSS_Lessons.exe, Install-HTML-Lessons.exe, Install-JSCode-Lessons.exe & Instructions.txt)
Double click the "Install_HTML-Lessons.exe" and extract the lessons to a location of your choice.
That should do it......................... Sorry for the headache Mac, problem is I completely forgot about the UNISA CD..
Thanky You..
