To second netmeg's suggestion, I don't understand why you're not asking AdSense about this direct? If I was down to $1 a day from $100 I'd be on the horn. What do you have to lose?
I think he said earlier that he'd contacted support and hadn't heard back yet. I think we'll all be interested to hear what they say.
