Urgent problems with upgraded outlook

[lukkie24]

Hi, I recently upgraded to office 2007 and when i went to outlook all of my emails and addresses were gone from it.
I also have outlook on a couple other different computers that access the same email, and i just needed to know if it would delete the messages and addresses from those outlooks also, because they are emails and addresses that i really need, or if it just affects the one outlook. I would appreciate it sooo much if i could hear back from anyone as soon as possible, thanks so much,
Jason

To to try clarify, Its Outlook express 6, i just need to know if the loss of one outlook express' messages and emails on one computer will be the same on the other outlook expresses on different computers (which havent been upgraded or changed at all) which all access the same email account, hope that clarafies somewhat, thanks again :) So bassically if changes to one outlook expess will affect others linked to the same email, thanks again :)
