We have discovered (as some of you have) an installation problem with a limited number of EA gamers who downloaded Battlefield 2: Special Forces through EA's Downloader. If your account is affected, you will see the following error when you try to install the expansion pack:

"BF2CDKeyCheck.exe has encountered a problem and needs to close. We are sorry for the inconvenience."
We apologize for this problem and are working quickly to resolve it. We will contact the gamers affected by this issue via email later today with a solution.
