I purchased this from Meritline (http://www.meritline.com/showproduct.aspx?ProductID=26876&SEName=mini-type-wireless-bluetooth-usb-adapter-class-1-bluetooth-v-2) and after installing the software that was listed on the page, it will not allow me to upgrade without paying the $25, even though it states on your site that upgrade is free. It also doesn't tell me anything about the hardware, serial, model, anything. Please help!
