Uploading files?

Hi,
When I upload files, I get the default WP upload box. It is not pre-populated with s2members file information. That's not a huge issue. However, all of my files reuqire "?s2member_file_download=filename.xxx." And, I am only able to upload zip files.
This is the first time using this plugin. I see it's potential. I just need some help getting past this.
Thanks,
Brian
