From the Cheat Happens FAQ (Link):
Q: Can I use my personalized trainers on more than one computer or will I be banned?
A: The protection included with our personalized trainers are meant to prevent public distribution and sharing, not to prevent you from using them on multiple home PCs. You are welcome to use them on multiple PCs. The only time your account may be banned is if the files are found on file sharing and/or bittorrent sites, or if we see an excessive number of different computers attemtping to use them.
* Up to 400 new and updated trainers monthly
* Manage and update trainers through one app
