Windows 7 Virtual Machine Freezing with VMware Player 12

I run a Windows 7 VM on a Windows 10 Host OS. I've been having issues with the VM freezing intermittently. The host OS does not have any issues. I have to shut down the VM through VMware controls, and restart it.

VMware Player Version

I looked at the VMware log to find this error -

I wasn't sure if this was strictly related at first, but I noticed this error was in the log every time the VM froze. I did some research online, and there was a post on the VMware forums (don't have the link at the moment), where someone suggested changing the send and receive buffers.

In device manager in the Windows VM, I accessed the properties for the network card. I changed the Transmit and Receive from 256 to 512. I did this a week ago, and so far, I have not had any issues.
