Unable to access Shopper Fields

[disco_dancer]

Hello
I am using VirtueMart 3.0.12 and Joomla 3.5.1(PHP 5.3.29 ).
Off late I am unable to access Shopper Fields and I am presented with a message
"Fatal Error in maincontroller admin.virtuemart.php: Couldnt find file userfields"
Have searched and am unable to find a solution for this problem.
Can someone please help me in the right direction so that I can access Shopper Fields?

Thank You

You should be using VM3.0.16 to work with Joomla 3.5.1  - test the update on a backup copy of the site.  And you PHP version really is too old.
