Logic Pro 7 & earlier Logic 7 with wrong XSKey?


Hi Everyone,

I have Logic at work and at home, and I have had for many years. I found a treasure-trove of old songs (in old Logic formats - 4.2 maybe?) that won't open in L9, but I know I can open them in v.7, save and open in 9. I still have a copy of v.7 on my computer, but I've lost the XSKey for my home setup when I moved several years ago. I still have the XSKey from my work setup though, which I no longer need. Can anyone tell me whether the key from work will allow me to open Logic7 on my home computer, or do the serial numbers/codes have to match?

Thanks for any help!
