new user registration & virtuemart

[lupinlady]

Joomla 2.5.14 VM 2.0.22c

user registration is OK on joomla end, created new user, manually enabled & activated, but in VM shopper management, if click on the new shopper, sends error 500

everything OK after manually entering user_id & shoppergroup_id into virtuemart_vmuser_shoppergroups.

is there a fix for this?
