i need help with my nokia 5800.
i bought a new PC, and I tried connecting it. but it says USB Device not Recognized.
So, I installed the latest nokia connectivity driver and restarted the pc.
Then I tried connecting the phone, windows detected it and installed the drivers.
I made a backup of the files in the memory card and then I format the mmc. (because of system error problems)
Then I tried putting the files back but windows says cannot find the specified files.
I tried putting different kinds of files in the mmc, but it still says cannot find the specified files

I disconnected it from the pc and then tried connecting it.
but windows says USB Device not Recognized..
Can anyone here help me?
