[Plugin: WordPress SEO by Yoast] Fatal error when editing page

WordPress version: 3.2.1
WordPress SEO version: 1.2.5

I did this: I moved my installation to another server. I also reinstalled wordpress seo.

I expected the plugin to do this: To work normally.

Instead it did this: When I try to edit a page, I get the following message:

Warning: require_once(/home/michalp334/domains/fmgroup-info.com/public_html/wp-content/plugins/wordpress-seo//admin/TextStatistics.php) [function.require-once]: failed to open stream: No such file or directory in /home/michalp334/domains/fmgroup-info.com/public_html/wp-content/plugins/wordpress-seo/admin/class-metabox.php on line 30

Fatal error: require_once() [function.require]: Failed opening required ‘/home/michalp334/domains/fmgroup-info.com/public_html/wp-content/plugins/wordpress-seo//admin/TextStatistics.php’ (include_path=’.:/usr/local/php5/lib/php’) in /home/michalp334/domains/fmgroup-info.com/public_html/wp-content/plugins/wordpress-seo/admin/class-metabox.php on line 30

The rest of the dashboard works normally and so does the site in general. When I remove wordpress seo, editing page works normally.
I checked the developers version of the plugin and it doesn’t solve anything.

Thank you in advance.
