Bought the game yesterday, logged on... Played for a bit... Was going to play a bit more earlier today, and guess WHAT? Yeah... "an error has occurred, please check your network connectivity"
Even though I am connected to the bloody internet, all ports ARE open, and no WiFi or anything...
WONDERFUL! And Crytek is bulling with: "We are aware that this is a known issue bla. bla. bla!"
