I see in the Homeseer web store they sell flash restore usb drives to restore HomeTrollers back to factory and re instal the software. I have a HomeTroller S4 but in the store they only have S2 and S3 units listed. What are my option for a S4. Also if it's available for the S4 is this file something that could be emailed to me and put it on a zip drive my self so that I wouldn't have to wait for shipping to Canada and the cost as well.
