IMAC 27in

First time I tried to use virtual box 4.3.6. Installed and created Windows XP virtual machine with 512Mb RAM and 10Gb virtual HD. Inserted original Windows XP CD in drive and pressed start. Got error:


Failed to open a session for the virtual machine WindowsXP SP2.
Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

Also tried with 1024 RAM with same result.

Virtual Box is now sort of stuck in this error.
Help please!!??
