Market Press plugin and the Media Library for Child Blogs on Multisite

I am creating a multisite that uses Marketpress on one of the child blogs. The child blog in question has an ID of 3. As a result all the uploaded files are saved to the following directory:

wp-content/blogs.dir/3/files

The Medial library cannot load thumbnails uploaded by the child blogs. The product detail pages show only a link to the image but the links themselves look like this:

http://www.website.com/files/2011/09/ios_image-221x300.gif

This doesn't load the image so the pages contain broken links to images both in the admin and on the user end. The only way to view the uploaded files is to manually adjust the link to look like this:

http://www.website.com/wp-content/blogs.dir/3/files/2011/09/ios_image-221x300.gif

The media library and thumbnail viewing works find in the main blog and on the child blog's product list pages. It breaks on the product detail pages.

Please help!
