Feedback, Complaints or Problems

I plan on doing some traveling soon and I don't plan on bringing my desktop. On my travels I am planning on going to visit my friend in aus so its out of the country that being said if I use his computer to play a game and want to download a trainer am I safe to do so without trouble? So long as I delete the trainer when I leave that is.. xD Not sure if the trainers have phone home options where if my ip changes or something if I will get my butt kicked by an auto system.

sure, no problem.
