Why can't I view the messages people sent me?

I am unable to view the instant messages I send and receive. Is there a way to solve this issue without having to uninstall and reinstall?

My email, Outlook Express (I really don't know if it is 2003 or 2002)wont receive emails my friends said they sent me? What is it and how do I fix it?

so far it seems to only be a problem with one person, i can send texts, recieve them, however when i open them in a conversational view it shows only the texts ive sent, so the only way i can read a text message on my phone is to hover over it and read...

I send email messages out but when I go to view them I cant find them in the sent box

I try to send messages, but I can't see them. Likewise, people try to send me messages but I cant see what they r sending me. Why?

i can reply to emails sent from our group but when i go directly to the website of our group at yahoo groups. i cant read past messages that were posted. i can make new posts only.

when i am on yahoo messenger, i type messages and when people on my friends list try to respond their messages wont come up. Please help me. Please send the answers to my mail
