MarketPress Sub-Site Global Product List Pagination - 404

I have a network installation of WordPress using MarketPress and on a sub-site, displaying global products on the homepage, the first page of products (items from other subsites) are displayed with a "next" link. When I click the link, I get a page not found error. I am using the following:

WordPress: 3.4.2
MarketPress: 2.4.6
GridMarket: 1.4.9

I have read several posts regarding pagination issues with MarketPress, tried several fixes including:

* Resetting Permalinks
* Using a the global product list shortcode
* and a few other modifications to theme / plugin - none of which worked and all changes were reverted.

Any assistance would be greatly appreciated.
