VMware workstation help

Hi I am trying to get vmware workstation running so I can run multiple windows xp on it.

I installed the ubuntu 12.0.4 LT kernel to fix the header problem but now I get these.

Now when I try to boot the virtual machine I get the error.

Could not open/dev/vmmon: No such file or directory.

Please make sure that the kernel module vmmon is loaded

Then Error failed to initialize monitor device

Then error: unable to change virtual machine power state:Internal error
