I've experienced the same issue at the time the new Workstation / Player just got released, but a few days after the arrival of the new versions the issues were solved. The problem was caused by heavy demand for the new software to the VMWare servers...
Can you access internet well on other sites and from other computers? Firewalls or other security related software might be configured so badly, mostly this happens automatically during automatic updates, that you are facing problems. A cleanup of your system, using cleanmgr should be sufficient, might solve the problem.
