Game 3205584 in Clash of Nations Map will freeze often

Game 3,205,584 in Clash of Nations 22 player Map will freeze often after only about 15 minutes of play- I have UK. Will shut down and restart game at that time. Has your server been overloaded last 48 hours?

A bit annoying after doing this umpteen times last 48 hours. Doubt if I'll ever play more than one game under these conditions. Or may just quit playing CoW ...
