Installation seemed to be successful, but no posts?

Wow, there seems to be alot people having issues with the 2.5 upgrade. Here’s mine:

I updated my site, and it seemed to upgrade just fine, however, once I login to the admin page, I can’t see any of my previous posts/comments/or pages. Oddly enough, the current number of posts/comments/pages do show up under the published filter and a few others, but nowhere else. On the page itself, I get the:

“Not found

Sorry, but you are looking for something that is not here.”

I dunno if this has something to do with permalinks, but nothing I had in the sidebars show up either. I run a 2nd blog, and integrated this database into that site temporarily to check it, and found that there’s nothing wrong with my database, but rather something I happened during the install.

Unfortunately, I just don’t know what. Anyone else having this problem?
