ok i cant install my zune software on my computer and i know someone already posted something about it but it didn't answer my question. ive tried installing it from the internet and also with a disc but neither has worked. i also tried getting an update that my computer offered for installing an update for zune but it didn't work either. when i try to install it goes all the way to where it says installing to your computer, it make take a while for different computers but then it just stops and asks if i want to cancel zune setup. if i say yes it closes the program and if i say no it just stays the way it was and does nothing and i can't get rid of it unless i restart my computer. what should i do?
