The virtual machine could not start. Make sure VMware Workstation is installed correctly and you have rights to run the software and to access all directories it uses, including directories in which the software is installed, directories containing the virtual disk and configuration files, and directories for temporary files.
How to solve it?
Restart your computer or stop VMware services that is running and delete all of the .lck folders and also the .vmem file in the vm guest directory. Guest directory is where your install the virtual machine. For my case, i install my virtual machine in "C:\Documents and Settings\user\My Documents\My Virtual Machines\Windows 7 - Base"
Now i'm able to start my VM. Thanks to suggestion http://darktraining.com/vmware/66/
