I have swapped the addon in the order. You should have gotten an email about it with links to download the new addon and license code. Let me know if you face any issues with it.
Can you kindly tell me which link you clicked to make the purchase. I checked the link in the admin UI and also the addon page at http://bulkwp.com/addons/bulk-delete-posts-by-content/ and both seem to be pointing to the correct url.
