hi, i have installed version 1.6.7 of MPE (using Windows XP) and I tried to connect my k550i but it doesn't do anything. When i press the scan button, he doesn't find any connected phones (i'm using USB connection). I took out the battery, restarted computer, etc.. but nothing works. I also don't know which COMport to use, or what to type there (COM1, COM2, ...) There aren't any comports available .. (it only says: COM)
