UBISOFT'S FAR CRY 2

I have purchased 4 copies of the PC version of FAR CRY 2. I have had a continuous problem with their game server. You can see many online games, few of which show a ping of 9999. One of these is my son's game. The server will not allow you to connect to these games. I have e-mailed Ubisoft about the problem and they keep saying that it is a problem in my end with the Internet security software and router firmware not being updated. The server also disconnects your account from the server in the middle of a game. I have done everything they recommend and then some to correct any problem that may be on my end.

In addition I have created a bootable hard drive to be used exclusively with "Far Cry 2", it has only windows XP (firewall disabled) and "Far cry 2" on the drive. This should eliminate any conflicts. I have also downloaded and installed the latest firmware on my router, as well as opening ports 9000-9004.

I am getting no resolution for this problem and think future customers should be aware of that lack of response from Ubisoft.
