Audio sounds as though it's skipping

[Lloyd Te Kani]

I think I may have stumbled across the problem. It seems my computer no longer recognises my CD/DVD drive. I tried to rectify this by getting it to test for the drive repeatedly but no luck and then after rebooting a couple of times, I thought the only thing to do was to back-up all my programmes and then un-install and re-install Hoster. Unfortunately because the computer thinks it no longer has a CD/DVD drive I can'y do this from my disk.

So that's where I am at present. Any further printable suggestions please apart from telling me where to put it.
