This patch resolves the following issues:

• Allows US players to join and play with International players online. Without applying this patch, some players may experience crashes or other problems when joining an international game.
• Resolves a crash that sometimes occurs when dedicated servers run multiplayer co-operative games

To apply this patch, simply double click the “SOAF Patch US.exe” file and follow the instructions that follow. Again, this patch only works with original US version of The Sum of All Fears.
