Get Fatal error: .../weight_countries.php on line 254

[t68]

Hi!
I run VM 2.0.10 on Joomla! 2.5.9 (have to go older version due to payment module compability).
But when I try to go to checkout or view cart I get error message:

Fatal error: Call to undefined method VirtueMartModelUserfields::fieldPublished() in /customers/a/4/0/hullingsilver.se/httpd.www/plugins/vmshipment/weight_countries/weight_countries.php on line 254

Note: this happens after I had to revert from 2.0.20, ended upp with installation problems for 2.0.1 so I had to manually upload component files. Did I miss something there maybe?

Thank´s for any help!
