'Creative 24-bit Sound Blaster Live!' Soundcard not working?

The Legacy drivers on my sound card keep on uninstalling somehow, and I reinstall them, but sometimes this doesn't work. Sometimes, I change output from 'Digital only' to 'normal', and this sometimes works. But now the sound just won't work. Can you help me? I have also got the 'latest' drivers, but this doesn't seem to work either.
