If you are receiving any Ubisoft Game Launcher, multiplayer connection issues, or are having trouble connecting to a multiplayer game please try the following:
1. Start by updating any anti-virus or personal firewall software that may be installed to your computer system. This includes your windows firewall as well as updating the firmware for your home router. If updating these programs does not resolve the issue, you may need to temporarily shut-down the associated program or bypass the router and establish a direct connection to your modem.
2. If it is not possible to shut-down your firewall, you will need to configure your router or firewall to allow the following ports for the best possible connection:
[TCP & UDP] 80, 443, 3074, 24650, 24659, 27050, 75054
[TCP] 13000, 13005, 13200-13999
Directions for configuring network ports are specific to the software and hardware being used, and can be found by visiting the manufacturers website.
3. You may also encounter problems due to applications running in the background on your computer system. When playing Ubisoft games, please be sure to close all running background applications before starting your game. You can find the steps for this listed below.
- Open your start menu and look for Run (Win XP), Start search (Win Vista), or Search programs and files (Win 7)
- Delete anything on the Open line that you'll find there, and type in the word MSCONFIG and press the Enter key to bring up the system configuration utility
- Look down the list of startup items (not the tab labeled Startup), and choose Selective Startup (if it is not already selected) (If you don't see this, make sure you've clicked on General, near the top of the window)
- Once you've chosen Selective Startup, uncheck 'Load Startup Items'
- Once you're done here, click Apply & OK, and let it reboot your computer
Try running the game again. If the game loads and seems to be working, the problem is most likely related to one or more programs you have scheduled to load with Windows. You can then revert the settings back the way they were, and in a trial and error fashion, disable some programs using the startup tab (in the msconfig utility) to try to find the culprit.
*Keep in mind that this is a temporary solution and any changes can be reverted by returning to the MSCONFIG utility and re-selecting 'Normal Startup"
4. There may also be certain restrictions set by your ISP. If you continue to have trouble, please contact your ISP for details on any specific restrictions on the previously mentioned network ports.
5. Try deleting your HOSTS file by following this path in Windows Explorer: C:\Windows\System32\drivers\etc. Delete the hosts file and try the game again.
If after you have tried the above and are still having issues please submit a ticket to technical support and post in this thread http://forums.ubi.com/showthread.php...rvers-downtime
