sry but all i can do at this point is advise you to
buy the game on steam - assuming you don't own it on steam yet.
If you own a retail DVD copy of Supreme Commander Forged Alliance then you can use the activation Key to get a free copy of supcom fa on steam with that as well.
Once you own the game on steam pm me again so i can lift your ban another time which will allow you to
link your faf acc to steam.
After that is done the uid check will not autoban your acc any more.
