No operation selected??

[Jon@NOWHERE]

I was working in mastercam this evening and while doing so I kept getting error messages saying that mastercam lost connection to the license file.  After the last error message Mastercam shut down.  Now I am getting a message saying the not operation was selected.  Now I can mastercam to do anything.   I get that message everytime I click on parameters.  If I try to add a new machine, nothing happens.

might be a licensing issue
if you have a mill selected and are trying to open lathe operations

It appeared to be with pulling the license from the server.  Those series of disconnects was the issue.  I shut my computer down and the next morning it was working as normal.
