Post not showing up in IE, but are in FireFox

Ok, I tried to upgrade to 2.7 last night, and it failed. I restored everything and got my blog page back up. However, you cannot see Januarys posts on the main page, nor can you see a certain page I pasted from Word when viewing the page from IE7. However, you can see it and everything looks fine when using FireFox. I went in and altered the page just to kinda sync it, with no avail. Has anyone had this problem before, and if so, what’s the fix? Thanks for any help y’all can give.
