You have to remember to run the new ip changer.. There is no installation process deleting your old and replacing it with the new version, you have to make sure you are launching the new one (which in simple terms means you can't go to the same place and launch the same ip changer as before), like in my case I now only have the new ipchanger in my downloads folder, and it isn't named ipchanger.exe, because I already had my old ipchanger there, it is called ipchanger(1).exe. Or if you have known file extensions hidden: ipchanger and ipchanger(1)
