We got the same message about 6 months ago (search my back posts for a whole thread about it). Except at that time they said that page only "WOULD be cut off in three days" if not changed. Three of us wasted an entire weekend (until G support got back into the office on Mon to respond to our e-mails) going over the pages mentioned with a fine-toothed comb and all of their policies and coming up with example after example of high-end websites and examples on G's OWN FAQ website which matched our pages to a T. When they got back on Monday, another reviewer took one look at it and said basically that he could see absolutely nothing wrong with that page the way it is, if that is how it was before. I assured him it was the same and invited him to review our pages stored for years on that big independent internet archives website, and never heard from them again. It is quite possible you simply got flagged, like we did, by a rookie Adsense reviewer trying to get his quota filled.
I've assumed they send this message out by robot on a random basis just to keep people in line (i.e see if you get paniced and change everything :). But my suggestion to anyone else with this problem, assuming you're not doing it on purpose and know what they are referring to, is not to agonize about it, but to write back, say you're anxious to cooperate and fix whatever the problem is, and ask for more specifics about what is wrong. Chances are you'll get another support person review and they'll either tell you the problem or just get rid of the flag.
