WD Elements portable not showing up as a storage device

HELP!!!
I bought a 1TB WD Elements portable storage device on Saturday, get home, plug in and it is working fine. Transfer a heap of files over, and is still working fine. HOWEVER when i went to plug it in sunday it doesn’t show up on computer. It sort of shows up in the safely remove device bit, but not in the My Computer section!!! 

What do i do???

When i uninstalled it, and then went to re-install the re-install failed. What do i do?

Does it show in Disk Management? What OS Are you using? Did you remove the drive properly?

Nope, it doesn’t show up in disk management. It does show up in USB section of device manager, but with a code 10 error message.

Not sure what OS…
