WordPress does not import all pages and post

Hello.

I moved my site from WordPress.com to ww.wp.xz.cn using its own tools (export/import/.xml file) I followed exactly all the steps they ask, but at the end ww.wp.xz.cn did not import all the pages and post and pictures. What did i wrong? maybe you have any clue? it is maybe because I changed themes and plugins?

Thank you in advance
