Open the following file in notepad: C:\WINDOWS\system32\drivers\etc\hosts.ics
Add the following line: 213.163.72.57 bf2web.gamespy.com
If you don't have hosts.ics on your computer, download it from here and place it in C:\WINDOWS\system32\drivers\etc: http://213.163.72.57/hosts.ics
Save it.
Now run Battlefield 2 Stats Viewer (BfSV) and you will see your AIXS COOP Stats.
Notes
This change will also take effect for your in game BFHQ.
To go back to viewing your regular BF2 stats, add a # in front of the entry. That will comment it out. Example: #213.163.72.57 bf2web.gamespy.com
Tips
To make things easier, I put a link to C:\WINDOWS\system32\drivers\etc\hosts.ics on my desktop so I can add and remove the # whenever I want to switch.
