Thanks.

yes, the blockhit-bypost-plugin allows you to place download restrictions on certain usergroups according to the number of posts they have made, optionally within a given number of hours.

the only difference with your requirement is that it does not reset when somebody downloads an entry.

go to vbulletin/admincp/products and plugins/download and upload plugins

in the import plugin definitions box (bottom of page), browse to extras/block-user-access subdirectory, then select the blockhit-bypost-plugin.xml file

either
go to ldm/admin/settings (to apply the controls to your entire ldm database)

or
go to category/edit category/control settings (to apply the controls to only part of the the database, i.e. this category and any subcategories)

scroll down to the bottom of the page and choose the parameters of interest
