my iTunes was working fine before I tried upgrading iTunes. After upgrading, when i first tried to open iTunes, it didn't open and said there was an audio configuration error. my audio seems to be working fine with everything else and i looked in Windows help and support about "audio configuration" and only found one thing. It was just about turning it on, and i did that, and it didn't help. I've tried uninstalling and reinstalling iTunes several times and that doesn;t help at all.

pleeease tell me what to do! i'm dying without my iTunes.
