Now, I have also completely removed the game, re-downloaded it, updated the ati drivers to the latest, running on windows 7 pro 64bit, and have a 45 mb pipe here at work to connect with.
I have been doing I.T. work for the last 35 years, and cannot see how it could be the internet or the connection, but I'll see what happens.
I'm running an AMD Radeon(TM) HD8490 video card with the latest drivers
