The Crashing Outlook Express

It took me 2 days to fix the outlook express and it can't be fixed. I tried the FAQ and HELP sections from Microsoft, won't work. I tried on other tips as well, never worked. I reinstalled my XP, never work. I gave up and installed Eudora Light Mail and trying to retrieve my old messages. Because of this, I didn't do anything much at all for this 2 days. It is really very irritating!!!
