hello,
Are fallowing these steps
1.installation of virtumart
2.installation of modules for virtumart
3.installation of giftregistry
4.Gift registry module
and then create gift registry and add products to it.

Thanks, I finally got it to work!

For anyone with a similar problem, my solution was:

-Backup all database tables that start with jos_vm_ except jos_vm_user_gift_registry, jos_vm_giftregistry_product_attr, and jos_vm_gift_registry into one SQL file with "add DROP TABLE" checked.
-Backup important VM files via FTP (components>com_virtuemart & admin>components>com_virtuemart).
-Uninstall all VM components, modules, and plugins.
-Uninstall gift reg component & module.
-Delete the three tables you didn't back up.
-Reinstall in the order posted above.
-Import the saved SQL file.
-FTP saved VM images for products and categories back to server (com_virtuemart>shop_image).
-Reconfigure VM.

Hope this helps someone...
