I'm working a lot with VMware virtual machines on Ubuntu 14.04 and sometimes VMWare "forgot" for some virtual machine. It often appears when VMWare freezes up for a few second.

Such machine cannot be booted up until kill it's process. When VM is used for some long-running tests it's not OK. So, is there any way how to open this process in VMWare workstation?
Showdown the VM. If that is a problem you could consider logging out and back in (to kill the VMware p[process). Then if there are and files or folders with a .lck extension delete them. This procedure has worked for me in the past when I receive the error message in you attached png file
As I have said killing the process is a bad idea. This VM is using for long-running tests and dirty OS shutdown is not acceptable.
The Workstation GUI runs in a process named "vmware" or "vmware.exe"
The VMs run in a separate process named "vmware-vmx" or "vmware-vmx.exe"
Killing a process "vmware-vmx" shuts down the associated VM hard - you dont want this.
Killing the process "vmware" only kills the GUI without stopping the VMs.
So in your case you can kill the "vmware" process and then restart it. Sometimes that does not work flawless and you have to take over ownership of the running vmware-vmx processes.
It is also a good idea to avoid using the WS-GUI to work inside VMs. For Windows VMs use RDP instead.
