I ran out of space on the main harddrive and now applications are crashing and acting weird.

I opened up mail and it said there was -an error in reading... now it is asking me to reenter the sign in information.. but the catch is that all my email messages etc.. don't show up...

are these gone, can I get them back etc..?

I think it is mail the file is I think called KICKER

I'd like to get the messages back..

if anyone knows how I can easily port everything to a larger hard drive that may help too.
