"Game process could not be started"

It's an issue with the servers. If you disconnect from the Internet, you can play.

I was having this annoying problem as well. I'm not sure I can even uninstall and reinstall since it was purchased as a digital download 3 years ago from a company that doesn't exist anymore. However, turning off the network connection worked like a charm. Thanks for the tip! Hopefully EA will fix the issue so we don't have to do this work around.

So it works even for download versions ? You don't need to be online to verify your copy ?

Yep. Tried your solution and it worked like a charm!

This issue should now be fixed.

You said if we still had problems (post 9-25-2012 post) to post here.... so here I am.  Only able to play if I start with WiFi OFF...

That's the thread that is monitored by the gurus.

It might be happening again ...

Please accept a solution if your issue is solved. XP is also appreciated.

I just started getting this error yesterday, no doubt something to do with the new patch that was released. grrr
