I downloaded at played Echoes fine at the office yesterday, but today when I downloaded and ran it here at home, it seems to be malfunctioning.
The game loads normally, though it seems a little sluggish, but I can't fire at all and nothing comes on-screen in the normal game. I can see the asteroid in crack, but cannot fire there, either. Autofire on or off makes no difference.
I was running Vista Ultimate x64 (SP1) there, and XP Professional x64 (SP2) here, and I'm going to update drivers in hope of fixing the issue.
