Problem with VMware

Hey I've been using Boot Camp for a while but I decided to use VMware because it runs with OS X at the same time. But whenever I choose to install VMware tools, I restart the virtual machine it's there but it won't let me change the setting to let me use the 3D acceleration setting, it says to turn it off, but when I turn off the virtual machine and then open it again, I have to reinstall VMware tools and it goes around and round. Very irritating and I really want to play some Counter Strike: Source.
