Mtp error when connecting via usb

view story

http://forums.androidcentral.com – I just updated my phone to jb via odin. I'm trying to root but whenever I plug in my phone to usb, I get a failed driver message, and my phone says mtp needs to close. Ive uninstalled and reinstalled the drivers, rebooted the phone and computer, and turned on/off usb debugging mode. Does anyone know what I can do to fix this? Thanks!
