FSX Question

Hello guys, me again with another instalment of 'Harry's technology woes' :lol:.

Just a quick question regarding Flight Simulator X. I had it installed on my old PC, and used the activation code it came with. If I install it onto my new PC, will it let me use the old code again?

I haven't yet tried because my new PC doesn't have a disk drive (it's an Ultrabook) but I'm buying an external one tomorrow.

Thanks in advance,

Harry :).
