Ohai all So, a few days ago I got the opportunity to play TF2 for 2 days. I downloaded it and played it a bit. It was pretty funny, so I bought it for 10 euro on steam, I used paypal to pay it. Nothing really changed, except for the note on steam which said '1,7 days left', that note dissapeared So, I did not have to install anything (only download it) and I did not get a ck key. What if my computer crashes, and I have to install windows again? How do I reinstall TF2 if that happens, without having to pay for it again? Do I have to make a backup from my steam folder or...?
