I found trough various operating systems and various fifa titles the main causes for connection issues to online play is that the [ .NET frame work ] is what I say is causing 99% of the problems and still is on Vista / win7 32/64bit.
On XP pro the service pack 2 included the .net frame work which was compatible for fifa 09/10 online connections, so there was no reason to install a sep .net frame work. But if you installed the service pack 3 for Xp, the online connections did not work. You had to reinstall/update .net 2.0.
Vista / win7 64bit uses a higher version of .net framework 3.1 - 4.0 and cannot install 2.0. So you will have problems connecting online on these OS.
Not too sure if there is a patch or update to fix this
Been trying to find a fix or work around - only to find that you kick back to xp
Will find it hopefully sooner than latter Just more online players on fifa 10 at the moment.
I downloaded FIFA 10 on windows 7 using Origin. Download and install went fine without problem. But when I start the game, I am getting "There is a problem connecting to the server. Please ensure your internet connection is active. If the problem persists try again later." I dont have any problem with network. I learnt that FIFA 10 is no longer available for online play but my problem is i can't play it offline also
