But err, dumb question maybe, but you did use two different cd-keys when you installed BF2, right?
Maybe I didn't..., can you tell somehow...?
I have an old BF2 copy that I bought in 2007, that is the old school CD package.
Earlier this year I bought a second copy of BF 2 through origin, which is of course a download - in order for us to play together - but my old computer was starting to show it's age so I decided to get a third computer - which means we now have three computers (the old computer and two newer, pretty powerful computers).
Maybe I did a booboo when installing..., investigating...
