Multisite Content Copier

Hi
I want to move 333 products from the main site of a multi site surrealvintage.com to another site within the network as the products are littering my shop.Can I do that with Multisite Content Copier as when I try to select the source (surrealvintage.com) nothing comes up. Only the subsites are listed. I have tried a few times and searched for answers but to no avail.

many thanks

Jon
