Satellite A300 PSAG4A music keys not working

Question

Hi,
I am new to this forum and actually Toshiba related problems in general. :P
I own a Toshiba Satellite A300-PSAG4A laptop running on 32-bit Vista. A few days ago, the Harman/Kardon illumination music keys on it suddenly stopped working. When I'm not using my laptop, I usually put it into Sleep mode and normally wake it up using these touch keys - however for some reason they randomly stopped lighting up and responding.
I tried the usual - rebooting the laptop and frantically testing the buttons but of course they are not responding. The keys and the laptop in itself have served very well up until now an I can't think of any reason why this is happening now.
I'm not super-computer savvy however I have done a bit of reading on the topic of these keys and wanted to try reinstalling the Toshiba Value Added Package method - however I could not find the TVAP file anywhere on my laptop.
Additionally, Toshiba does not seem to offer support for my laptop series (A300-PSAG4A); their download section only caters to the ST series. Please correct me if I'm wrong - I could be searching right or whatever.
I performed a System Health Report to check if it's a driver-related issue and it came up with the following :
Two error messages stating that "The device driver for Base System Device has not been installed" and one stating that "The device driver for #UNKNOWN# has not been installed.
I don't know what any of those mean or if they are relevant to my problem.
Please help?

Hi, thanks so much! That was really helpful, I didn't know Toshiba has separate sites for different continents. I live in New Zealand, so that'd be why it's an Australian series.
However I mentioned earlier that I can't find the VAP file anywhere on my computer. I have since done additional reading up the subject and learned that the package also enables the FN keys - which don't seem to be working at all. I'm pretty sure my laptop doesn't have the file on it (it is second-hand so the previous owner might have uninstalled it) unless there is some special way of searching for it? Where would it normally be located?
