vmware中出现这样的错误

我在F8中安装好了vmware workstation 6后，启动正常，建了一个XP，但是在启动虚拟机时出现这样一个错误：
Version mismatch with vmmon module: expecting 167.0, got 161.0.
You have an incorrect version of the `vmmon' kernel module.
Try reinstalling VMware Workstation.
然后是：
Failed to initialize monitor device.
再接下来是：
Unable to change virtual machine power state: Cannot find a valid peer process to connect to.
还有：
Failed to reply to the dialog: Pipe: Read failed
以上分别是四个error对话框，谁能给看看是怎么回事，有没有人遇到过？
