Label printing - Avery fields not matching to labels

I'm having the same problem-my labels printed fine last week. All of a sudden, like Ben said, they progressively bump up. I have followed the fix suggested above, but it still does it, and also, on the right margin of the first page, half of the last character is cut off. Only on the first page, the rest of the left-right margins seem OK. This also happend in programs that are not Word.
