Okay, many of you, like me, have a issue with servers. Most users who play on Windows 7 that click on a server, nothing will happen. But I've found a solution.
1. C:\Ace of Spades\client.exe -aos:\\ <----------------Copy that code, and save it somewhere you'll remember it.
2. Go to play AoS.
3. Right click > Copy Link Address
Then you'll receive a code like this aos://99999999
4. Open the fire with the Code from step one.
5. Paste the aos code numbers you copied from the server, onto the code where is from step 1
Ex: A. C:\Ace of Spades\client.exe -aos:\\
B. C:\Ace of Spades\client.exe -aos:\\99999999
6. Click your start button(windows icon on left corner).
7. in the blank
8. Now paste the new code in(ex. C:\Ace of Spades\client.exe -aos:\\99999999), and hit enter.
9. Have fun
