DA wont work if the original site have prefixes in it´s database

I had a site with a prefix on the database tables, I choose it when I installed the drupal (right now, I can't remember why I made it, rsrsrs). Well, the Domain Access didn't generate it's own tables because the prefixed names of the original tables, the Domain Access module try to copy the original tables as I could understand, but only looks for the tables names without the prefixes, so, if the original table is called "my_block", Domain Access will return a error saying that it could not find the "block" table. I hope you understand my terrible english :-(.
