Hi the AAAA League require's you to use UAC3 it can be found here -:

Logon to UAC3 -
Click on Play
select your game Medal of Honor AA
For Match ID just key in your own made up name - in a match we would give you an id.
Click on start scanning and then launch your game as normal.
After you quit the game your Screen shots are automatically uploaded.
You can review your screen shots via UAC3 - if other players had used your same id then their screen shots would be grouped with that id which you would be able to view

as were a few of my players i know. Appologies for that jon. My UAC3 seemed to be working fine when i got it started but obviously something went wrong somewhere...?? not sure tbh... think i lost my screenshots or they were black screenshots ?? and i'm on windows 7 as well which as i understand also creates problems. I'm gonna re-install UAC3 and start again i think. 
Hi all RANT time - Still seeing players INCLUDING my own clan not using UAC3 WHY!!! - an example here from friendly MEGA v WOV - Players Playing in screen shot and players who used UAC3 big difference - mass failings on both sides - this is just an example..... I can pick any League match scan from any clan and find the same result!!!
CLAN ADMINS including myself - Players MUST use UAC3 - failings to use UAC3 = "Clan admins kick their own players OFF!!!"
