I am all the time getting message!!

Generally it occurs when your browser times out.
See information and how you can change it in the registry ... HERE

It which browser/program, do you receive that message? (IE. Firefox...?)
I have never seen such a message nor had reference to it.
Or, perhaps it was "The page you are looking for cannot be found, try refresh". That can be caused by an internet connection error, or a mistype. Could you post one of the links, so that we may examine it for a possible script error?

But you could try clearing out your cookies. When you hit "Refresh" in the View tab, at the same time, hold down the shift and Ctrl keys.
