After loading the program and the driver on my desk top computer, I found that it would not communicate with my handset. I then tried it on my notebook computer and the same thing. I then went online and downloaded a program and driver upgrade. I then installed the upgrade. I now had two icons on my screen. The new program would not run because the old program was still on my computer. I then had to uninstall the old program and reboot the computer. Once I did that, the new program links to my phone and everything now works fine. I use Easy Media Creator 10 to convert my music CDs to MP3 files. I can then use the Handset Manager to edit the song and upload them onto my phone to creat a ringtone list. Overall, the program works fine for me after I finally got it running.
