Installation problem

By installation from beginning are two error messages:

1. On the site -

No Shop Currency defined! Contact the administrator, if you are one go to dikomneva.ru/administrator/index.php?opt...w=user&task=editshop

2. And the second on the Virtuemart settings -

Your Virtuemart installation contains an error: No user as marked as vendor. Please fix this in your phpMyAdmin and set #__virtuemart_vmusers.user_is_vendor = 1 and #__virtuemart_vmusers.virtuemart_vendor_id = 1 to one of your administrator users. Please update all users to be associated with virtuemart_vendor_id 1.
