Step 1. Try disabling your firewall.
Step 2. Disable the firewall protection on your router and put the router in game mode. You may also forward ports if you would like. Remember these problems could be the server or person you are connecting with.

This could be the result of several things so I recommend you take the following actions.
Step 1. Update your video card drivers.
Step 2. Install the latest version of the Microsoft C++ Runtime Files and DirectX
Step 3. While your at it, update to the latest version of the .Net Framework and then reboot.
Step 4. Change the resolution of the game by using the settings file. You can find this in the following location:

C:\Program Files\Konami\Pes 2011\ (Windows 32bit users)
or
C:\Program Files (x86)\Konami\Pes 2011\ (Windows 64bit users)

Now go lower the settings and see if that works.

Step 5. If you think the video is crashing you, install the K-lite Codecs Pack.

Now see if it works… if it does not and you are not on Windows XP:

Step 6. Right click the exe or shortcut file, go to properties and then choose the compatability tab. Run the game with compatiability for Windows XP SP3.

Possibility 1. This could be due to the fact that you installed a 3rd party patch that corrupted your computer. Remove it and try launching again.
Possibility 2. You may need to update your drivers, directX, C++. Do that if you havent. If that still doesn’t work than try running it was XP coma

This can be due to you not correctly patching your game. Delete your old scoreboard files.

This could be due to the fact that you used a bad patch. Remove the patch and try again. A lot of the modification programs are still be worked on to fix this.
