The View Connection Server authentication failed. A secure connection to the server '(null)' cannot be established.

I am a remote VMware user and have never had problems until yesterday, I have been using the log/link on etc for almost a year and now I get this message when trying to log in

The View Connection Server authentication failed. A secure connection to the server '(null)' cannot be established.

The client that I am trying to connect with says it is not on their end, but mine?

I am using windows 8 and am not computer literate.

should I uninstall and then re-install the VMware program?

I appreciate any help
