my hotmail app i downloaded seems to have deleted all my emails

I recently checked my emails on my computer and they were all there. I then decided it would be nice to have access to them on my phone. I downloaded the hotmail app onto my motorola razor, and signed in. as soon as it signed in I went to inbox and it had 0 messages. I got a little freaked out and checked my computer again. The emails were completely deleted. I also checked the deleted emails to see if they were there, its as if I had signed up a completely new account. Is there hope in getting these back, Im possitive I have been on in the last 120 days.
