If no Render Camera option is available in the Render Settings page of www.renderRocket.com you will not be able to launch your render job.  Default viewport cameras can not be rendered for 3D Studio Max until you create a camera from the viewport using the 3D Studio Max application.  When you have created a camera and re-uploaded your scene file, a camera option will be available in the Render Settings and you will be able to launch your 3D Studio Max render job.
