I downloaded a video and tried to play it on WMP (I think I have 11 on this computer I don't know what version Vista Home Premium has) and I can't play the file instead it's telling me to check my sound system and all software associated with it.
Having done what it has told me everything appears to be up to date all sound systems are enabled and in working order and yet still I can't play this file.
Any ideas what can I do? It's really frustrating!
