I get this message every time I try and load FIFA 2005...
And how do I go about disabling it?
There's another thread about this in the forums somewhere, 1st posted within days of the release of the PC version I think.
It's basically related to whether you've got CD copying software on your computer - eg Nero - and I guess the idea is that you have to disable it before Fifa will run.
So - type "nero" into the search box of either the 2005 or 2005 Support Forums and you'll find the thread.
