import problem – missing files

I am migrating my site from one hosting company to another. I have the lastest version of wordpress running on the new host as well as the old one. I go to the export page and download the xml file to my computer. I then sign in to my new wordpress blog. At the import page I click import. Everything seems to be going fine. I then click “view my website”. The new blog has all of the older listings but I am missing the last six months of posts. Aug 07 to Jan 08 do not appear. What am I doing wrong?

The file size is about 650k.
No images imported.
The first month with images was Aug 07.
I received no error codes at any time.

Could using images have stopped the xml file from including all the posts from that time onward?

I’m into guessing right now.
