I had a similar problem. The way I solved it was by using patches put out by end users who - out of charity - did VMWare's work for them.
The patches fix vmmon and vmnet so that they will function.
The instructions for the basic patch may be found here: https://github.com/mkubecek/vmware-host-modules/blob/master/INSTALL
For later versions of the kernel, you may need to install a different variant of the same repository found here: https://github.com/nan0desu/vmware-host-modules
First, what version of the kernel, and what version of VMware workstation pro are you using? What is your host OS?
