This is really getting to be a big pain in the you know what.....

I got the error AFTER I had disabled and then re-enabled my Avast. I looked in the virus vault and there was NOTHING for CF in it.

1. un-installed CF
2. deleted the program file
3. downloaded and installed CF again
4. added the path C:\Program Files\Z8Games\CrossFire to the scanning exceptions in Avast then added the path to the back up drive copy as well
5. got all the updates
played the game for 1 day and then got the error again after a Windows update came thru

1. looked in my Avast virus vault and found NOTHING
**ERROR: File is changed: W[2007] L[0] crossfire.exe**
2. looked in my "backup" but the files I needed were not there - deleted idiot backup
3. uninstalled the game
4. deleted Z8games folder

7. turned off my Avast antivirus
8. re-downloaded and then installed the game: file I got was CrossFire_Setup_v1085
9. restarted my computer

1. Found my Avast was back on so I checked it, nothing found in the virus vault

At this point I am obviously going to be forced to download and yet AGAIN to re-install the damn game. My Avast isn't causing the problem, nor are Windows updates. That's the reason I have kept a running log; so I could document what my computer was doing. To me, there seems to be some sort of issue with the damn HGWC plain and simple.
