Restart your main OS , and try to turn on the cirtual machine from the power state and not from the hibernation state in case it is.

If this didn't work , try to create a new VM machine and attach the old VHD to it and try to power it on.

start VMplayer by right click "run as admin"

Try restart VMware Authorizantion Service

Here is a link to video instruction: How to fix error: VMware Player cannot connect to the virtual machine - YouTube

I hope it helps

Thanks, Continuum, You saved my time.
