Upgraded to 3.3.2 via Fantastico and all my posts have disappeared

The title says it: I upgraded via Fantastico and all my posts are gone. The previous version I was using was 2.1, and I had never upgraded because I was afraid something like this would happen.

I only upgraded now because I am not really using the blog anymore, so it wouldn’t be the end of the world if this happened, but I would prefer to restore my posts.
