Was using Nokia PC suite but decided to trythe new Nokia suite. After D/Led it I am not able to see my C5-03 with either of the two programs on my PC. I have tried every thing recommended but nothing works.Even eraced both programs and D/Led the new suite and when that didn't work I went back to the old suite which didn't work either. Also I am getting no indication of the C5-03 on my computer when I look at the Explorer files on my Win 7 PC unit.
Uninstall the 'Nokia Connectivity Cable Driver' thru' Windows Control Panel.. Then rebbot the PC. Connect the phone again thru' USB and wait for the drivers to re-install. Make sure PC is connected to Internet in case latest drivers need to be downloaded.. Check now...
Did exactly as you wrote and had the same results. It isn't recognizing my C5-03. Tried both programs and neither worked. Have used Nokia PC on my old cell ,had no problems. Had no problems with my new C5-03 until I went for the 'New" Nokia suite and now can't get anything to work. I believe the new Suite did something ??
One more thing you may try is Uninstall the Nokia Suite.. and install the version available
