[help] comodo stops vmware workstation 6 in winxp 64bit

Host system: windows xp 64bit sp2
My vmware workstation 6.0 can work properly in my system without comodo professional 3.
But after i install comodo, vmware fails to power on slave system, and the vm itself can’t shut down either.
In xp 32bit vm can be open but can’t be shut down properly either with comodo.
All the comodo setting is default.

Could you please tell how i can use both of them without confliction? I need your help.
Thank you anyway.
