What the hell?? Email suddenly is getting all messages from 1 year ago.

[THE-COPS]

Ok what the hell is going on with this thing. My Yahoo mail has always worked fine. I have it set to get messages from ast 30 days and newer. It has always worked well, up untill today. Now when I send/receive, it starts downloading messages from May of LAST year up til today. I checked settings and sure enough its still set at 30 days. I cant get my friggin email because it queues over 500 messages from my inbox history on yahoo to download. I have to stop it. Can someone tell me whats going on witht this? Aside from manually going through al of my old mail onine and deleting messages, what can I do to remedy this? I have messages in there I want saved, so going through it isn't very practical. I shouldn't have to.
