My little knowledge... but worth a try....
Same thing happened w/ me.. just yesterday.. and I was running it as admin as well... but still didn't help.
So here's what I did.. start-->%temp%--> deleted all the temp files... rebooted my PC.. then hooked the phone again and tried it.. worked.

For whatever it's worth.. give it a shot if you still having the same problem.

Cheers!
