Right after a recent discussion on here i have bought an ebay vag com lead. When installing/setting up i get as far as selecting the device manager, right clicking usb>serial and bring up the properties. But, heres my problem, when i click on the advanced tab to try and select a COM port between 1 and 4, it says "you must have write priveleges in the registry for this device in order to modify the device advanced settings????? Someone please help, im not too clued up on PC'S
