Not come into play

Hi.
I have big problem
I have on many occasions the problem, see picture ...
http://prntscr.com/74d585
What can I do to get back in the game.
Not all cards that.
An uninstall and reinstall of Silverlight brought no success.
plz help

Does it happen with all maps/scenarios or a particular one? I had this problem but just with one particular map,

Try to do this on a regular basis:
(1) clear history (and cache) of browser
(2) Clear Silverlight on regular basis
(3) Flushing the DNS cache: go to Windows start => cmd => ipconfig /flushdns

Thanks for your suggestions.
Have made all these things, including flushnds.
Everything worked, but unfortunately the map does not work still.
Are there perhaps other ways that the Map is working again?
Incidentally, it is only a map.
Had but at another map ever ....
