OverCharger: Sorry, It´s the same issue, but It´s difficult to explain well because of my bad english.
I already tried to run the game on win98 before the opening of this thread.
Thanks anyway.
My english again.
I tried to run the game on win98 compatibility mode.
I had this problem on my first run, it was caused by Windows Firewall popping up "behind" the application. I Alt-tabbed out of the game and selected unblock, then alt-tabbed back into the game and everything was fine.
I was thinking about this again, and I may have had to press Ctrl-Alt-Delete (bringing up the task manager) rather than Alt-Tab.
