Unfortuanately i'm at work now so wont be able to try these solutions till i get home later tonight.
Sometimes, my laptop boots up and works for a few minutes. If it does this time then i'll try the scan 'Johndrew' suggested. Otherwise, i'll have to try making friends and then ask to borrow their discs.
I'll give you more feedback either tonight (if the missus stops her yapping and lets me work) or tomorrow.
Can't check out your link from this company comp, as they seem to be blocking it (nice aren't they), so i'll check it when i get home. Not too sure if my lappy's worth spending money on though as it's far too old.
