Ok,
Here the deal.  I do alot of traveling and I would like to install BF2 on my laptop.  But the only copy I have right now is on my main rig sitting at home.  Can I use the same copy that Iv'e got on my desktop, also on my laptop as long as both copies arn't going at the same time?

I was wondering if I could do that because I play CSS using Steam.  And they allow me to do that as long as both copies arn't running at the same time.  I didn't know if BF2/EA would let me do that as well.  Or am I doomed to go out and spend another 50 bucks on another copy.

Thanks
