Hi, I purchased a set of these used 2k gyres off ebay with the wifi controller. I however cant register and control the devices because there is a stupid registration lock on the device. I've contacted the seller who says he never registered them (which makes no sense as it is a forced registration to use the device) and he has since stopped responding. Contacted CoralVue support because the website says a Hydros representative can unlink it so I can re link and use them and they all say they cant due to "legal reasons". Anyone know anything else I can do? Never thought I'd run into this issue buying it used? I could get my money back through ebay but I'd rather just get them working. Thanks in advance
