Device won't connect to DM

I was wondering if anyone has ever had the problem of not being able to connect their 9700 to the computer.

I am using the USB cable that came with the 9700 and using the latest version of DM. For whatever reason, the computer is saying that my device has malfunctioned and is preventing me from uploading any information to my computer or downloading from my computer.

Can anyone help find a solution to my problem? I can't update any new files and it's really restricting me to what I can and can't do.

Any information would be greatly appreciated.

Thanks!

Just wanted to update my thread...

I decided to connect my 9700 to my ancient computer with Windows XP. For whatever reason, it recognized the phone, loaded DM and connected my phone to the DM.

Crazy I know, but my brand new laptop which previously had no issues with my original 9700, won't connect to my 2nd 9700 but my ancient computer will.

What gives?
