Im going to buy but...

I want to buy this so much but i dont live in the us and my dad is staying there for like 2 months and he said he will get this but b4 he does i need to ask something.It says only one pc can use the hack if you get it once so will i be able to use it if my dad gets it there and doesnt use it then i can use it here on my pc?

if he buys it there but doesn't download the client then yes, but you can't both use it because it's account sharing

please repeat this in clear thought out english
