I've tried a few, but any download from vCampus seems to fail for me, throwing me an error page:
Either the site is offline or an unhandled error occurred. We apologize and have logged the error. Please try your request again or if you know who your site administrator is let them know too.
The vCampus Download Center is experiencing some issues right now. Our IT team is working on that. Sorry for the inconvenience.
