Thanks for your inquiry.Very sorry. This is a technical limitation. Protected files served by PHP scripts ( i.e. s2Member ) cannot be resumed at this time. That is, technical details involved in supporting this get VERY hairy across various browsers. We ARE planning to test resume-able downloads using the technique documented here, but this is not ready for production just yet. See:
http://www.awesomephp.com/?Tutorials*16 ... tions.htmlSo, resume-able downloads are not possible at this time ( i.e. s2Member v110815 ). With s2Member-protected files, Customers must begin the download again from the beginning in the event that a connection failure prevents it from succeeding the first time around. s2Member won't count this against a Customer though, they just need to start over is all.
