unable to launch virtual box

[fldadof5]

Hi,

I'm a bit to using virtual box.

I have this error:

Stderr: VBoxManage: error: Failed to create the VirtualBox object!
VBoxManage: error: Cannot register the hard disk '/Users/scott.hall/VirtualBox VMs/app01/box-disk1.vmdk' {13a575a9-445a-4a5e-ae9f-1941acf55b63} because a hard disk '/Users/scott.hall/VirtualBox VMs/app01/box-disk1.vmdk' with UUID {13e64984-ebe5-43ca-8450-2f39f84aef32} already exists
VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBoxWrap, interface IVirtualBox

I tried to fix it per what I've read, but this doesn't work:

Scott-Hall:devops-2 scott.hall$ VBoxManage internalcommands sethduuid "/Users/scott.hall/VirtualBox VMs/app01/box-disk1.vmdk"
VBoxManage: error: Failed to create the VirtualBox object!

VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBoxWrap, interface IVirtualBox

And I can't launch virtual box app either, it fails with:

Failed to acquire the VirtualBox Com Object.

and points back to the same error message. Any help would be appreciated.
