yahoo mail connect?

[tankthemuppet]

hello, i am obviously new to this board, but have been enjoying adium ever since i got it about a year ago.
I have loved it because it tells me when my yahoo account has new mail, pretty much consistently.

BUT recently it has stopped giving me mail notifications.... soo.... I:
-tried updating adium to newest version
-tried restarting
- tried changing mail notification off then on again
-tried deleting account and re-entering it

none of these have worked so far... i can't think of what the problem might be! eep!
anyone have any ideas for fixes or have similar problems? please help! thanks so much!
