Hi Bob
I'm sure you can figure it out.
Bob. I wish I could help you better. But I'm not sure what you mean
Are you
1, trying to download CFS2? That would not be wise
or
2, are you installing from original CD Rom?
or
3, are we talking about a copied install that you have saved on a backup harddrive?
If you think there is some thing happening when Windows or some other program updates stuff.
You are probably
right on target.
I can't imagine someone would try to hack into your computer just to spoil your hobby, unless, maybe, someone close to you is trying to tell you something!
You will have to roll the system back to before the problem started.
You've done that a few times now, it should be getting easier, you can do it again.
This time, be sure to disable automatic updates,
Have the system ask you what updates you want to install.
Only install security updates. look at the what the other updates actually are. If you deem them meaningful install them in small groups to try and pick off the one that is buggy.
