Is my account alright?

I am about to purchase aimware, but I haven't  been using this site account for a long period of time. (This is the only account I own.) Can someone please verify if I can safely buy cheats here?

P.S: Can I share this cheat with only one of my buddies? So can 2 people use this cheat at once?

Yes, you can safely use this account.
No, you can't, the cheat is registered only to you and your hardware: this means that only you will be able to use it.
